Setting HTTP request headers

Who can tell me how to set HTTP request headers,for example ,If-Modified-Since,i only know how to get If-Modified-Since in servlet and use it.

Hy,
Headers are provided by the Browser you use. He controls the Content of it, eg. the accepted File types, the Browser name and type, HTTP Version used, ...
You can, however, add your custom Headers with the addHeader Methods in HttpServletResponse. Then, you can read them out on the Client, eg.
using Jsp, and react on the Client based on the given values.

Allow-http-request-headers-from Question

I have a crossdomain.xml file in place, but am still getting this error:
"Security error accessing url"
I searched the web and is it true that because I am accessing a SOAP web service I need to add this to the crosssdomain.xml file:
<allow-http-request-headers-from domain="MYDOMAINHERE" headers="SOAPAction"/>
Is there anything else from a crossdomain.xml file perspective, or anything else in general to be able to access these web services from my Flex app?
Thanks for your responses.

The SWF is at MyDomain.com (for example).
The crossdomain.xml file is on the 3rd party web service provider at the root of their web server, and it correctly has an entry to MyDomain.com.
The exact error is "Security error accessing url".
I read on the web that when accessing SOAP web services you need to add these entries to the crossdomain.xml file:
<allow-http-request-headers-from domain="MyDomain.com" headers="SOAPAction"/>
Is that the case and is there anything else extra I need to do to get web services to work in this case?
Thanks Alex, for helping with this.

How do I add my own headers to the default set of request headers without using a plug-in?

When I open HTTP Live Headers, I see that there are default request headers that go out from the browser to the server. I want to add a Pragma header with a specific value to be sent. This will help me to remove a plug-in from my arsenal and thereby be sure that all the request headers are going as a part of the request.

I think this probably requires an extension. As far as I know, there is no preference you could change in about:config or user.js to "add a header".
Or are you generating the request with JavaScript?

Help needed about HTTP Request Headers

HI All,
Regarding HTTP RFC 1945 I have to use headers request-line and message is there any functionality in Servlets or JSP to access both them. I used “request.getHeaderNames()”, which return the headers “ACCEPT,ACCEPT-ENCODING ,ACCEPT-LANGUAGE ,CACHE-CONTROL ,CONNECTION ,CONTENT-LENGTH ,CONTENT-TYPE ,COOKIE ,HOST ,REFERER ,USER-AGENT” but not request-line and message.
Kindly provide the help to access them.

I had a look at RFC 1945. It gives an example of what it calls a Request-Line:GET http://www.w3.org/pub/WWW/TheProject.html HTTP/1.0But as far as I can see it doesn't describe this anywhere as being a header. So it doesn't surprise me that getHeaderNames() doesn't return it.
I'm also surprised you're even trying to access this low-level information with a high-level tool like a servlet. You could probably reconstruct it with various servlet methods, though. You know the method (e.g. "GET") and you can find out the URL from various methods of the HttpServletRequest.

HTTP Request Headers

Is it possible to use form data passed from a form outside of
a Flex application? For example, there's a simple HTML form that a
user fills out and then submits which points to a Flex application.
Is it possible to access the data sent via a POST or GET? Here's a
simple HTML form example to help illustrate my question:

<form name="Foo" method="POST" action="index.html">
</form>

I don't think so. That example assumes you want to embed an
HTML page inside Flex. I'm trying to access data sent to a Flex
application through a form submission. In the example I posted, the
form would POST the field data to the Flex application
(index.html). I had hoped there might be some sort of internal
function within AS that lets you access the field data passed to
the Flex application. Something like:
URI.getRequestHeader.fields

Setting http header in as3

hi all,
I did face the similar issue and i cant set request headers
in flash AS3. Actually i m trying to download file from S3 Amazon
Bucket, which can only be allowed if custom header is set in a
request. I m trying to set that but when I check the request
Packets from Etheral or WireShark, the request doesnt contain any
of mine custom header.
here is my flash download code;
var headers:Array = new Array();
var authHeader:URLRequestHeader = new
URLRequestHeader("Authorization","AWS: "+accesskey+":"+signature);
var dateHeader:URLRequestHeader = new
URLRequestHeader("x-amz-date",date);
request.url = domainUrl+objectkey;
request.method = URLRequestMethod.GET;
headers.push(authHeader);
headers.push(dateHeader);
request.requestHeaders = headers;
trace('request:'+request.requestHeaders.length);
try {
loader.load(request);
}catch (error:Error) {
trace("Unable to load requested document.");
Remember I uploaded crossdomain.xml in the bucket with polies
mentioned as under;
<cross-domain-policy>
<allow-access-from domain="*" secure="false" />
<site-control permitted-cross-domain-policies="all"/>
<allow-http-request-headers-from domain="*"
headers="*"/>
</cross-domain-policy>
In order to download file from Amazon Bukcet the Request
Packet should be;
GET /<bucketname>/<filename>HTTP/1.1
x-flash-version: 10,0,2,54
User-Agent: Shockwave Flash
Host: s3.amazonaws.com
Authorization: AWS:<accesskey>:<signature>
x-amz-date: <date>
but after doing all the above work my final request sent to
amazon;
GET /<bucketname>/<filename>HTTP/1.1
x-flash-version: 10,0,2,54
User-Agent: Shockwave Flash
Host: s3.amazonaws.com
:( no custom header here;
plz can anyone suggests
Text

Thanks alot Raymond for advice, it works, actually i tried
with POST but without data. and now I came to know that Flash
silently convert POST request to GET if no data is provided :).
stupid Flash.
but there is still a problem, as I mentioned that I am trying
to retrieve files from S3 Amazon AWS data server which only allow
GET request with custom header. and when I tried what you have
suggested in the reply, Amazon gives Error in Response b/c the
Signature which is used as a Key b/w the client and amazon server
can only be created with GET request.
Is there any possibility to send GET request from Flash with
custom header b/c in my case, I need to send Http Request with GET
method and along with custom header. :( Th Amazon doesn't accept it
with POST.

Handling Compressed HTTP Requests on Tomcat 6.0.14

Hi All,
     I am sorry to post this problem here if it not relevant, but I have investigated so much but couldn't come up to a solution.
     I have developed a Web service using JAX-WS 2.1 and successfully deployed on Tomcat 6.0.14. My Web Service accepts and sends large data. So i have tried to use data compression on Tomcat.
     *I have successfully performed sending compressed HTTP Response from tomcat but not able to configure it for accepting compressed HTTP Requests.* If you need more details about my problem read further.
     I have successfully configured my tomcat server.xml like below:

<Connector
     port="8080"
     protocol="HTTP/1.1"
     connectionTimeout="20000"
     redirectPort="8443"
     compression="on"
     compressionMinSize="20"
     compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/css"
/>     Tomcat will send compressed responses to clients when ever it is willing to accept compressed data otherwise server will send plain responses.
     Now on words when ever server will get HTTP Request with *"Accept-Encoding: gzip"* set it will send compressed response to that HTTP Request and plain response otherwise. All modern web browsers accepts compressed data.
     This is working great.
     *My Problem is I want tomcat to accept and understand compressed HTTP Requests also*, for that I have compressed my request with java.util.zip.GZIPOutputStream and set HTTP Request Property like below:
"Content-Encoding: gzip"
"Accept-Encoding: gzip"     But server returns error code 500( Internal Server Error). The server log shows error like:
com.sun.xml.ws.streaming.XMLReaderException: Unable to create StAX reader or writer

Solved it by going to the temporary folder for netbeans:
C:\Documents and Settings\creator\.netbeans\6.0\apache-tomcat-6.0.14_base\logs This is where it is placed on my install drive. This is where it deploys the builds , not in the C:\Program Files\Apache Software\Tomcat 6.0.14 as I would expected.
It seems that it is an IDE bug after all it is not cleaning the old logs. For today I found a 64 mb log (localhost.2008-01-02.log).
Thanks

You will get a faster and much better response if you move this post into the "Data Center - Application Networking" forum where they deal specifically with load-balancing issues.

Setting HTTP headers when using xrpcc

I am using xrpcc to compile my WSDL and am using the resulting code to access my web service. When accessing a web service this way, is there any way that I can set HTTP headers before the method is invoked? If not, is the only option to build all of the SOAP requests by hand and ditch all of the nice things xrpcc does for me?
Along those same lines, is there any way to get a dump of the SOAP envelope that is being sent when the xrpcc generated methods are invoked?
Thanks.

Damn, I need to read the HTTP headers that came in along with the SOAP JAXRPC message. So it looks like a similar problem. And noone answers this question. Damn.

Setting the header in http request object

I am facing a problem while trying to test a particular flow of my application.The details are given below:
The controller servlet of my main application reads the header "Referer" from the request object and then based on this it forwards the request to appropriate servlets.For testing my application I am writing a test servlet which receives a request object from a test jsp and sets all the necessary attributes in the request object and passes this request object to the doGet () method of the main application's controller servlet. But while trying with this I find that the main controller fails to forward to the correct servlet because it receives incorrect referer information. So my question is how can I set my customised "Referer" in the header of the http request so that the application's controller servlet forwards to the correct servlet?Is there any means to set the request header in servlet or jsp?

As far as I know you can't change the request in a servlet or .jsp, but you can in a Filter. Wrap the original request object in a wrapper class before passing it to chain.doFilter().

Adding custom headers to a HTTP Request

Folks,
I'm wondering if it is possible to add custom headers to a HttpRquest. In other words is it possible add new headers to the HttpServletRequest. We have addHeader methods for Respones but not Requests. Servlet Filters dont seem to let u do it too.
I saw that the deprecated HttpRequestWrapper (catalina.jar) has addHeader methods, but I get casting issues. Is there any proper way to accomplish this ?
Thanks a bunch for your time n help folks..

Unfortunately I would need to add the information as a HTTP Request HEADER and not as a request attributte. I would need something like request.addHeader(obj1,Obj2), which is not available.

I am getting an error Bad Request Request too long HTTP Error 400. The size of the request headers is too long.

When I sign into Methodintegration.com my data base I can get in ok. When I sign out I get the following error: I am getting an error Bad Request Request too long HTTP Error 400. The size of the request headers is too long. If I close Fire Fox and go back in it will work one time and then I get the same error message.

Setting http headers in weblogic

Hi,
We would like to know how http response headers can be set in weblogic server
8.1.
This information is urgenty needed.
Quick response will be appreciated.

Thanks for the pointer. Didn't realize you had to construct the notification from scratch in order to add custom headers.
The only thing missing is how to set the HTTP verb that notification hubs sends down to the client. This is needed for
X-WNS-Match as this header needs to be sent with an HTTP delete per the MSDN docs.
For those interested here's a code snippet to send silent toasts to the phone. For universal phone apps you will be using WNS rather than MPNS.
private static async Task SendNotificationAsync()
var hub = NotificationHubClient.CreateClientFromConnectionString("<connection string with full access>", "<hub name>");
var toast = @"<toast><visual><binding template=""ToastText01""><text id=""1"">Hello from a .NET App!</text></binding></visual></toast>";
var headers = new Dictionary<string, string> { { "X-WNS-SuppressPopup", "true" } };
var notification = new WindowsNotification(toast, headers);
await hub.SendNotificationAsync(notification);

If I access the website of Cebu Pacific Air I get as reply upon entering a search request "HTTP Error 400. The size of the request headers is too long.", but if i use private browsing i do not get this reply. This refers to Firefox 5.0 on ubuntu 11.04
I have tried to resolve this through deleting history and the cookies, but i always get the same reply. Although if i use firefox (ubuntu) private browsing or Firefox on Windows 7 i do not get this error message.
What causes this error and how do i resolve this?

Setting HTTP headers from Xcelsius

Hello,
Does anyone know whether it is possible to set HTTP headers during Xcelsius web service or XML data calls?
Regards,
Gilbert

Hello Victor,
Both the XML data and the web service calls i am doing end up at agents that act on the content of the HTTP headers. For instance, the SOAP node that is listening to my web service calls uses the soapAction HTTP header for further routing of the call. That header is specified in the WSDL, but i need to be able to change it without changing the WSDL i.e. i would have to set the soapAction header. My end app can listen to the SOAP headers but the intermediary only HTTP headers.
Regards,
Gilbert
