HTTP headers vs HTTP URLs

Could someone please explain the very subtle difference between HTTP headers vs HTTP URLs?
Thanks.

Hi,
The URL is the resource location with or without additional parameters that will be requested - e.g. www.cisco.com or http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&needs_authentication=yes&forum=Data%20Center&
The HTTP headers on the other hand are additional parameters that are part of the HTTP protocol. They define things like Cookies, the referrer etc. A list of headers can be seen at http://en.wikipedia.org/wiki/List_of_HTTP_headers.
It is also possible to add your own headers - usually prefixed with X-.
If you look at the dissection of an HTTP conversation captured by Wireshark you'll see how the headers are used.

How to set Custom HTTP headers in HTTP binding?

How to set custom HTTP headers before sending the Rest based request in HTTP binding?

sharon38_74 wrote:
they said that our internal application needs to send a "login request" to etran via SSL with the user's information encoded in base 64 format. etran captures the HTTP header containing user authentication and authorization information, and parses the required information from the HTTP header.
My question is that how I set user information in HTTP header? From my understanding, once I am able to set the user information in HTTP header, it is in base 64 format?Your application need to act like a proxy. You can invoke a HTTP request programmatically using java.net.URLConnection. You can set request headers using URLConnection#setRequestProperty(). Also see the API docs: [http://java.sun.com/javase/6/docs/api/java/net/URLConnection.html]. You only need to know the header field name where to set the Base64-encoded value in. You need to Base64-encode the value yourself.

How to set the HTTP headers in HTTP Binding to call RESTful service

I'm calling a RESTful service from the SOA Composite through a BPEL process. The RESTful service need few values to be set in the HTTP header to authorize the request. I tried several different options like setting the headers in the invoke service etc., but in vain. Apparently, the web service call fails for not having header information.
I have burnt several days on this. Can somebody help me to get through this please?
I'm using SOA composite 11.1.1.4 on WLS 10.3.4.
Thanks in advance.

Generate PDF using Managed Bean with custom HTTP headers

Background
Generate a report in various formats (e.g., PDF, delimited, Excel, HTML, etc.) using JDeveloper 11g Release 2 (11.1.2.3.0) upon clicking an af:commandButton. See also the StackOverflow version of this question:
http://stackoverflow.com/q/13654625/59087
Problem
HTTP headers are being sent twice: once by the framework and once by a bean.
Source Code
The source code includes:
- Button Action
- Managed Bean
- Task Flow
Button Action
The button action:
<af:commandButton text="Report" id="submitReport" action="Execute" />
Managed Bean
The Managed Bean is fairly complex. The code to `responseComplete` is getting called, however it does not seem to be called sufficiently early to prevent the application framework from writing the HTTP headers.
HTTP Response Header Override
* Sets the HTTP headers required to indicate to the browser that the
* report is to be downloaded (rather than displayed in the current
* window).
protected void setDownloadHeaders() {
HttpServletResponse response = getServletResponse();
response.setHeader( "Content-Description", getContentDescription() );
response.setHeader( "Content-Disposition", "attachment, filename="
+ getFilename() );
response.setHeader( "Content-Type", getContentType() );
response.setHeader( "Content-Transfer-Encoding",
getContentTransferEncoding() );
Issue Response Complete
The bean indirectly tells the framework that the response is handled (by the bean):
getFacesContext().responseComplete();
Bean Run and Configure
public void run() {
try {
Report report = getReport();
configure(report.getParameters());
report.run();
} catch (Exception e) {
e.printStackTrace();
private void configure(Parameters p) {
p.put(ReportImpl.SYSTEM_REPORT_PROTOCOL, "http");
p.put(ReportImpl.SYSTEM_REPORT_HOST, "localhost");
p.put(ReportImpl.SYSTEM_REPORT_PORT, "7002");
p.put(ReportImpl.SYSTEM_REPORT_PATH, "/reports/rwservlet");
p.put(Parameters.PARAM_REPORT_FORMAT, "pdf");
p.put("report_cmdkey", getReportName());
p.put("report_ORACLE_1", getReportDestinationType());
p.put("report_ORACLE_2", getReportDestinationFormat());
Task Flow
The Task Flow calls Execute, which refers to the bean's `run()` method:
entry -> main -> Execute -> ReportBeanRun
Where:
<method-call id="ReportBeanRun">
<description>Executes a report</description>
<display-name>Execute Report</display-name>
<method>#{reportBean.run}</method>
<outcome>
<fixed-outcome>success</fixed-outcome>
</outcome>
</method-call>
The bean is assigned to the `request` scope, with a few managed properties:
<control-flow-rule id="__3">
<from-activity-id>main</from-activity-id>
<control-flow-case id="ExecuteReport">
<from-outcome>Execute</from-outcome>
<to-activity-id>ReportBeanRun</to-activity-id>
</control-flow-case>
</control-flow-rule>
<managed-bean id="ReportBean">
<description>Executes a report</description>
<display-name>ReportBean</display-name>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
The `<fixed-outcome>success</fixed-outcome>` strikes me as incorrect -- I don't want the method call to return to another task.
Restrictions
The report server receives requests from the web server exclusively. The report server URL cannot be used by browsers to download directly, for security reasons.
Error Messages
The error message that is generated:
Duplicate headers received from server
Error 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION): Multiple distinct Content-Disposition headers received. This is disallowed to protect against HTTP response splitting attacks.Nevertheless, the report is being generated. Preventing the framework from writing the HTTP headers would resolve this issue.
Question
How can you set the HTTP headers in ADF while using a Task Flow to generate a PDF by calling a managed bean?
Ideas
Some additional ideas:
- Override the Page Lifecycle Phase Listener (`ADFPhaseListener` + `PageLifecycle`)
- Develop a custom Servlet on the web server

Thank you!

The problem was that the HTTP headers were in fact being written twice:
1. The report server was returning HTTP response headers.
2. The bean was including its own HTTP response headers (as shown in the question).
3. The bean was copying the entire contents of the report server response, including the headers, into the output stream.
Firefox ignored the duplicate header errors, but Google Chrome did not.

Rewriting http headers and url for Oracle Applications

We are running Oracle financial applications and need to provide access to users on the Internet. We can do that fine except for people behind tightly controlled firewalls that only allow port 80 and 443. Oracle insist it has to run it's apps using SSL on non-standard ports like 8001 and such which means many people can't get to them. So to make sure everyone can get to the apps I need to preset it on port 443. Changing the apps/servers isn't an option for many frustrating reasons so I'm looking for something that can reverse proxy and rewrite headers and url's. The hard part is the headers and all urls in the web pages need to be changed on the fly because Oracle hard codes everything with absolute paths.
Can someone give me some advice on what Cisco product(s) may be able to help?

After bringing this up with my Cisco rep it was recommended I look at the AVS 3120 box which is supposed to support the header/url rewriting I need. Can anyone with experience with these boxes let me know if I'm being steered in the right direction? The documentation doesn't seem to specifically mention this ability or if it does it's worded in a way that doesn't make it obvious.

HTTP Headers - enabling caching and compression with the portal?

Has anyone configured their web server (IIS or Apache) or use a commercial product to flawlessly cache and compress all content generated by the portal?
Compression and caching is critical for making our portal based applictions work for overseas users. It should be doable, just taking advantage of standard HTTP protocols, but implementing this a complex system like the portal is tricky, we seem to be generating different values in the HTTP Headers for the same types of files (such as CSS).
We are running Apache so can't take advantage of the built in compression capabilities of the .net portal. We are running the java vervion. 6.1 mp1, sql server 2000 (portal, search, collab, publisher, studio, analytics, custom .net and java portlets on remote server).
Basically our strategy is to compress all outgoing static and dynamic text content (html, CSS, javascript), and to cache all static files (CSS, javascript, images) for 6 months to a year depending on file type.
Here are some links on the subjects of caching and compression that I have compiled:

Hi Scott,
Does Weblogic platform 8.1 supports netscape? We have developed a portal which
works perfectly on IE but it dies in netscape. Is netUI tags not supported in
Netscape?
Pls reply

Netscape 4.x and below have terrible performance with nested tables.
The

If IE and/or a recent version of Netscape/Mozilla is not possible then
there are
really only two options:
1) Faster client hardware - not likely to be an acceptable solution.
2) Minimize the number of portlets and the complexity within the portlets.
Neither of these solutions are a great answer, but the 4.7 series of
Netscape is
getting pretty old. Having said that, we've got customers who want to
continue
to use IE 4 :)
Again, though, this problem is, I'm afraid out of our hands. It is the
client
rendering time that is the issue.

b/c it takes so long to load some of the webapps. What the pages willdo when
loading is that the headers will come up and when it gets to the bodyof the page
it seems to stall and then comes up all of a sudden. For some of thepages it
takes 6 seconds and for others it takes about 24-27 seconds.
We have suggested using IE only but that is not an option with allof the customers
and getting a newer version of Netscape is also out of the question.
Any suggestions would be greatly appreciated.--

Can we pass values to custom headers through HTTP bindings in BPEL?

hi,
I have an urgent requirement where I have to pass values to custom headers of HTTP url through HTTP bindings in bPEL.
Is it possible? Say I have a http url http://localhost:80/test.
I need to post xml over the above HTTP url as well pass some values to the Custom Headers Variables.
Can I achieve this functionality thorugh BPEL or not?

Hi,
My requirement is exactly the same as yours, can you please let me know what did you do to overcome the Oracle Forms Default change password screen.

Exclude http headers from reponse??

Hi all,
I post data to a server and get response[in xml] back like this
Socket theSock = new Socket(serverhost,80);
PrintStream ps = new PrintStream(theSock.getOutputStream());
ps.println("POST /url HTTP/1.0");
SAXBuilder builder = new SAXBuilder(); //==<< get reponse
Document doc = builder.build(theSock.getInputStream());
.at builder.build I've got "SAXException: Parsing Error : The root element is required in a well-formed document" .
that because output from theSock.getInputStream() is
HTTP/1.1 200 OK
Date: Wed, 04 Jul 2007 10:14:54 GMT
Content-Length: 105
Content-Type: text/xml;charset=UTF-8
Connection: close
<resp>
<status>200</status>
<description>ok</description>
</resp>I know that if i use HttpURLConnection the response InputStream will not contain http headers. But I'm just curious that with Socket, Is there any trick to get only content from InputStream?

There is no trick except to use the HttpUrlConnection class. That�s why it was created. It wraps the socket and parses through the headers for you. The socket is very low level and all it sees are bits over an input stream (TCP / UDP). It does not know or care about HTTP which is a protocol on top of TCP.

Passing HTTP Headers from BPEL to a RESTFul service in SOA 11g PS2.

Hi All,
We have the following requirement.
We need to pass the following headers to RESTFul service.
x_invensys_wss_username = "Some UserName"
x_invensys_wss_password = "Some Password".
I tried to first pass username and password properties by following below post.
Attach Http headers in BPEL Process
Specifically below steps..
Hi,
If you are talking about how to invoke a secured webservice...please follow this...
After creating the reference for your secured webservice in your composite, right click on the composite and say configure web service policies...
Add the security policy named "oracle/wss_http_token_client_policy"
And also, for the reference, create two binding properties
1. oracle.webservices.auth.username
2. oracle.webservices.auth.password
For the above two properties, provide the appropriate values.....
Please test the same after making this changes and let me know....
Thanks,
Narsing Pumandla
======================================================
Somehow i don't see the headers getting added to the call.
The service i am calling don't really need these headers.But the URL we will be calling shortly for the real application need them.
Can someone let me know whether this SOA version supports this or not.?
If yes , Then what is the best way to solve this issue.[i.e Able to send hardcoded values and also user specified values.]
Thanks,
Sid.

I am using this URL : api.geonames.org/postalCodeSearch?postalcode=90110&username=siddhardha
I see below message in audit trail.Not sure why the headers are not visible.
Am i missing something which is very fundamental.?

Accessing Java webservice (XML over http) via WCF or HTTP adapter with content-type and authorization HTTP headers with POST method

Hi Team,
I need to access Java web service which is simple service and accepts and returns XML over HTTP. No credentials are needed to access the service. We need to pass following two HTTP headers (Content-Type and Authorization) along with XML request message:
<GetStatus> message is being constructed in the orchestration and URI is constant to access.
Which adapter shall I use to get the response back? I tried using WCF-WSHttp with Security Mode = Transport, and different options of client credential types but every time, error returned stating:
System.Net.WebException:
The HTTP request is unauthorized with client authentication scheme 'Basic'. The
authentication header received from the server was 'Basic realm='.
Authentication failed for principal Basic. Message payload is of type:
String
In Fiddler, request looks line following
POST <https://URL/GetServiceReopnse HTTP/1.1
Content-Type: application/xml
Authorization: Basic cmVmU3RhdHN2Y19kgeRfsdfs=
Host: <Server name>
<GetStatus XMLNS="http://server.com/.....">
<OrgId>232323</OrgId>
<HubId>3232342323</HubId>
</GetStatus>
MMK-007

First, you should not use the HTTP Adapter because it's been deprecated and replaced by WCF.
Start with the WCF-Custom Adapter and select the customBinding.
You should start with the textMessageEncoder and httpTransport and go from there.

Parsing out HTTP headers

I'm writing a simple HTTP client and server. I'm looking for an efficent way to parse out the HTTP headers that the server sends. The code below is working for me at the moment but i don't think it's the correct way of going about it.
import java.io.*;
import java.net.*;
import java.util.*;
public final class RequestTEST {
    public static void main(String args[]) throws Exception
           final String CRLF ="\r\n";
           try {
               Socket mySocket = new Socket ("127.0.0.1", 5306 );
               DataOutputStream out = new DataOutputStream(mySocket.getOutputStream());
               InputStream in = mySocket.getInputStream();
               System.out.println("Enter a file name to request");
               String filename = Console.readString();
               String request = "GET /"+filename;
               System.out.println("Sending "+request);
               out.writeUTF( request );
               int bytes = 0;
               boolean header = true;
               while((bytes = in.read()) != -1 && header)
                    if(bytes==10) //Line Feed LF
                         bytes = in.read();
                         if (bytes==13) //Carriage return CR
                         header=false;
               System.out.println(bytes);
               in = mySocket.getInputStream();
               byte[] buffer = new byte[1024];
               FileOutputStream oStream = new FileOutputStream(filename);
               while((bytes = in.read(buffer)) != -1 )
               System.out.println(bytes);
            oStream.write(buffer, 0, bytes);
            oStream.close();
               mySocket.close ();
           catch (Exception exp ){
               exp.printStackTrace();
}I know the code is a little rough but i'm just developing the idea. Only started it today.
Any suggestions or tips on the overall approach to this would be much appreciated.

Maybe use the HttpURLConnection and then getHeaderFields().
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.HttpURLConnection;
public class URLTester
     private final static String PROTOCOL = "http://";
     public static void main(String args[])
          if ( args.length != 1 )
               System.out.println("Usage: java URLTester <url>");
               System.exit(-1);
          String urlString = args[0];
          try
               // Create URL object from the URL string
               URL url = new URL(PROTOCOL + urlString);
               // The connection object has information that may be
               // retrieved without parsing the data returned
               HttpURLConnection conn = (HttpURLConnection)url.openConnection();
               conn.connect();
               // Get an input stream from the URLConnection object
               InputStreamReader isr = new InputStreamReader( conn.getInputStream() );
               BufferedReader in = new BufferedReader( isr );
               System.out.println( conn.getHeaderField(0) );
               int headers = conn.getHeaderFields().size();
               for (int i = 1; i < headers; i++)
                    System.out.println(conn.getHeaderFieldKey(i)
                         + " : " + conn.getHeaderField(i));
               String line;
               while ( (line = in.readLine() ) != null )
                    System.out.println( line );
               in.close();

Acrobat Reader X stores PDFs in Temp-folder even when HTTP-headers say no-cache no-store

After updating from Acrobat Reader 9 to 10 we have noticed that PDFs viewed in the browser are left behind in the Temp-folder even after the browser has been closed.
Http-headers in the response from the server
Cache-Controls: no-cache,no-store,max-age=0,post-check=0,pre-check=0
Content-Type: application/pdf
Content-Disposition: inline; filename="xxxxxxxx.pdf"
Expires: 0
Pragma: no-cache
Folder: [User-folder]\AppData\Local\Temp
Filename-format: PDFxxx.tmp
Browsers: Firefox 3.6, Opera 11, Safari 5
Plugin: Acrobat Reader 10
Simply add a .pdf extension to the file and open again in Acrobat Reader. Since the server has set headers indicating that this PDF should not be stored locally, it is a severe security hole leaving traces of this PDF on the filesystem.
Is this a problem Adobe is aware of? When can we expect this to be fixed?

Hi Michael,
Thank you for you quick response!
In Acrobat 9, I cannot find the PDFs in the Temp-folder after the browser has been closed.
In Acrobat 10, PDFs are left behind in the Temp-folder even after browser close.
To me, this looks like a bug in Acrobat 10. Would you not agree?

Using custom http headers in SOAP sender adapter

Hi,
my problem is exactly the same as reported [here|Re: SOAP Sender - Extract Header Values;] and [here|Variable Transport Binding - Soap Sender;
Basically I'd like to send through the soap sender adapter some custom http headers. I check the necessary options in the advanced tab (set adapter-specific message attributes and variable transport binding), and in the variable header one I put x-StoreCode, which is the same http header I send to PI.
But I won't see anything in the dynamic configuration section when the message is persisted in PI.
Very surprised that I've seen this issue is a common problem others have faced before without success.
Thanks!

Hi Michal,
the extra info I'm trying to send separated from the message is an http header, not part of the query string.
If I incorporate the extra info as a parameter to the query string like this, for example:
http://host:50000/XISOAPAdapter/MessageServlet?senderParty=&senderService=S1&receiverParty=&receiverService=&interface=Int&interfaceNamespace=urn:test&x-StoreCode=13&nosoap=true
Then I can see the value in the dynamic configuration section:
<SAP:Record namespace="http://sap.com/xi/XI/System/SOAP" name="SQueryString">senderParty=&senderService=S1&receiverParty=&receiverService=&interface=Int&interfaceNamespace=urn:test&x-StoreCode=13&nosoap=true</SAP:Record>
But what I'm trying to do shoould be possible, according to sap help:
http://help.sap.com/saphelp_nwpi71/helpdata/en/fc/5ad93f130f9215e10000000a155106/content.htm (section Define Adapter-Specific Message Attributes)

Encoding problem (Umlaute) in HTTP-Headers

Hi!
I have a servlet that is being called by another server via a POST request.
The request contains user data in HTTP-headers, and whenever there is a
German Umlaut in the user's name, it ends up garbled. :(
The requests character encoding is set to 'ISO-8859-1', according to the servlet
requests getCharacterEncoding() method.
I try to copy the value of a header variable into a String like this:
headerNameValue = request.getHeader("headerNameKey");Which, unfortunatly, doesn't work. For example, the value "G�nter" becomes "G��nter".
Shouldn't the API take care of the encoding, when the CharacterEncoding is set
right in the servlet call?
It looks like it interprets the ISO88591 data as Unicode?
BTW, I'm on a WebSphere 5 server, with Java 1.4.
I've been tearing my hair out on this one for days, so any help is highly appreciated.
Thanks a lot!
Andreas

A header variable with the key 'accept-charset' is not sent.
Only 'accept-encoding', with the value 'gzip, deflate'.
Like I wrote in my first post, the servlet request's character encoding is set to ISO-8859-1,
according to the getCharacterEncoding-method.
I have kind of solved this for now by converting the String 2times back, like this:
try {
     headerNameValue = new String((new String(headerNameValue.getBytes(),"UTF-8")).getBytes(),"UTF-8");
} catch (UnsupportedEncodingException e) {
      logger.error("Fehler beim Umwandeln der Umlaute im Benutzernamen.",e);
}                    }This code converts the '��', that my servlet receives, back to '�'.
(The first conversion changes the '��' to '��', the second the remaining '��' to '�').
While this seems to work, I don't think it is the right solution, and I still don't understand what's going on. :)

Andreas

Biztalk 2013 WCF-WebHTTP Adapter - Outbound HTTP Headers

Hi
I have a requirement to connect to a service using the WCF-WebHTTP adapter that requires authentication to be passed in the Headers.
A usercode and password is sent in the intial header and a security token is returned in the response header.
This security token is then used in the header of each subsequent call to the service.
I could not find anything in the documentation about getting and setting the "HTTP Header" data using maps or variables or using variables in the "Outbound HTTP Headers" on the adapter transport properties.
Any help on this would be gratefully received.
Malcolm

You can set the outbound HTTP header in WCF-WebHTTP adapter by 2 ways
1) At adapter level Change adapter properties
2)Changing Message context property at Orchestration or at pipeline
Its been well documented here
