HTTP Compression causes HTTP2228: Response content length mismatch

Dear All,
My application use iPlanet 6.1, recently we have enabled HTTP compression for the webserver.
Which inturn does not picking up style sheet and results with bad look and feel on front end.
On the back iPlanet logs we see some errors like
warning (23569): for host xxx.xxx.xxx.xxtrying to GET /zbank2/css/zbank.css, finish-response reports: HTTP2228: Response content length mismatch (315 bytes with a content length of 945)
Could you please help to resolve this problem
Thanks,
Jude

Can you send your css file? I tried it on Web Server 7.0 update 3 seems to be working fine.

Content length mismatch

Hi all
I'm getting these type of errors when accessing content on my web server
Dows anyone know why this could happen???

thanks a lot !

yep, those files are served by a backend App Serv, actually, the web server load balances 3 Application Servers.
I have no network connection problems, but somehow the files between Web and App servers are not completely sent.
I also have these 2 errors, i dont know if they're related

SunOne Web Server 6.1 and JSP response content-length

Hi,
I am looking for help for a problem in my previous post
http://swforum.sun.com/jive/thread.jspa?threadID=58612.
It seems to me the only significant difference of the response to the same jsp file from 6.0 and 6.1 server is the content-length header.
6.0 response has the content-length header;
6.1 response does not have the content-length header.
HttpUrlConnection::getContentLength() returns the actual content length of the 6.0 response;
HttpUrlConnection::getContentLength() returns -1 for the 6.1 response.
Here is the dump,

In my test env, 6.0 and 6.1 are installed on the same machine (Win2K), using the same directory as web root, same http port. Browser runs on a different machine.
Thanks

Hi, elving
This is good information. Thanks very much.
Actually, I am not using SSL, just plain http connection with basic auth. It might be the cache-control header that causes the head ache. 6.0 response does not have the cache-control header, but 6.1 has.
The interesting thing is that adding a servlet mapping on 6.1 solves the problem.
I will take a further look tomorrow.
Cheers,
Harry
I doubt the problem has to do with the Content-Length
header.
I'd guess that you're using SSL. Are you? If so,
you're almost certainly bumping into a known bug (or,
as Microsoft describes it, a "feature") in Internet
Explorer. Microsoft article KB316431 at
http://support.microsoft.com/default.aspx?scid=316431h
as some information on the problem. As the article
points out, the problem occurs when Internet Explorer
needs to invoke an external application to handle a
file that was served over SSL with Cache-Control:
no-cache and/or Pragma: no-cache headers.
A work around would be force Web Server to send
Cache-Control and Pragma headers that don't include
the no-cache directive. For example, the following
lines could be added to the obj.conf configuration
file:<Object ppath="*.jnlp">
Output fn="set-variable" set-srvhdrs="Cache-Control:
private"
Output fn="set-variable" set-srvhdrs="Pragma:
private"
</Object>Fortunately, it sounds like you've already
found another viable work around.

Html filtering content length issue

I am using the Filter type="filter-hhtml" to tets stripping out EMBED and OBJECT tags from html pages. It is working fine but when the resulting page is loaded the browser (konquorer in this instance) reports a content length mismatch and shows an error message. The new page is shown. When I try and view the html source I get the same error and never get to see the source. When I try under Firefox and IE it works fine. I was just wondering if it was possible (or even necessary) to change the content-length to accurately depict the resulting size of the page after filtering?

Checkout send-error.So I can place a drective like this (assuming I have a 403.html file in that location):
Error fn=send-error code=403 path=/opt/sun/webproxyserver/html/errors/403.html
I assume I place this inside my Object definition for my template ... is that correct? I plan on placing it at the bottom of my template. Does its location in the Object definition matter? I am sorry but the docs are not real clear (at least to me) on hard details so forgive my questions.
just for clarity is this a proper template definition(I have 3)?NameTrans fn="assign-name" name="BlackList" from="http://.*yahoo.*"
NameTrans fn="assign-name" name="WhiteList-level1" from=".*://64\.215\.169\.*/.*|.*://.*gblx.net/.*"
NameTrans fn="assign-name" name="WhiteList-default" from=".*://.*/.*"
The one named BlackList is just for testing purposes (which I can't seem to get to work either.
Isn't the following legal? When I have a template match it should go to this object and execute directives right? It should see and execute the deny-service right? Why is it not?
<Object name="BlackList">
Service fn="deny-service"
Error fn=send-error code=403 path=/opt/sun/webproxyserver/html/errors/403.html
</Object>
thanks again

HTTP PUT Request for File Uploads is returning a response header with content-length = 0

After upgrading from CF9 to Coldfusion 10, I'm running into an odd issue, with `cURL` calls to a webservice that used to work.
We are using an HTTP PUT Request with multipart="no" so that the request header content is the file itself, now the data is being sent properly in the content but it has a ~8k limit. This is fine for smaller files but some files are 60kb etc.
Errors are odd too, near the 8KB limit we get a bad gateway error 502, and above that the webpage errors with a connection reset.
It works fine with multipart="yes", but in a PUT request the file's data isn't even sent since it's looking for `httpparam formField` , the content-length from the target page's Headers show a content-length of 0 which causes `cURL` to fail with an error (56): http://curl.haxx.se/docs/manpage.html
Here's example code to reproduce:
<cfset sFilename = "C:\999\test4.txt">
<cffile action="readBinary" file="#sFilename#" variable="fileRead">
<cfset oFileInfo = GetFileInfo("#sFilename#")>
<cfhttp           url="localhost/Clarence/diff_elt_test_output.cfm"
                              method="PUT"
                              username="******"
                              password="******"
                              multipart="yes"
                              result="oHttp">
          <cfhttpparam type="header" name="Content-Type" value="text/plain" />
          <cfhttpparam type="header" name="Content-Length" value="#oFileInfo.Size#" />
          <cfhttpparam type="body" value="#fileRead#"/>
</cfhttp>
<cfdump var="#oHttp#">
Dumping the response via GetHttpRequestData() shows that the header's content-length = 0 and content is blank.
Whereas POST requests work fine, cURL has a -F form option which is our fallback but a solution to this would be great.
Here's what I've tried:
1. Changing CF post request limit sizes (64MB+)
2. Changing IIS config web/webserver http runtime and security.request filtering request limits to much higher values
3. AJP Connector between IIS and Tomcat has a default 8KB header limit, I changed that to 64k on both sides, still nothing
Also am I missing something fundamental here? I thought at the network layer a packet is split up and rejoined, so large content in a http request body should work, what's wrong with Coldfusion 10?

I am familiar with java.net package and know how to
Read and Write Streams.
However, what I do not know is what string
represntation of PUT or POST resquests is?It's HttpURLConnection.setRequestMethod("PUT") or ("POST").
Also you have to setDoOutput(true).
Then you set the content type, possibly encode the input, set the content length, and write the file data to the stream.
Using a Jakarta package may be easier, however.

Missing Content-Length in HTTP response

Hi All,
I am experimenting with developing websevices using Sun Java Application Server. I have a working webservice using BEA Weblogic and I would like to have it ported to SUN. The application works like this: A client (Tuxedo application program) sends an XML document to the webservice, in response the websevice parse this document and based on certain fields it send back another document.
The problem is that the SUN application does not return the content-length in its response and hence the requesting client rejects the message. Can anyone help?? Below is the response from both SUN and Weblogic:
Weblogic

As can be seen the Content-Length is missing.
Thanks for your help.

Is there an option in Sun Java Application Server to include Content-Length in response to a client request? If not is it possible to generate this information from the service code?
Thanks.

Content-Length Header Missing in Http Response

Hi folks,
Our application uses JSPs and Servlets. To solve a TCP level probelm, we would like to ensure that each response sent from the WebLogic Server includes a content-length header. All the pages are dynamic and therefore we cannot explicitly set the content-length.
To ensure that WebLogic has the opportunity to set this header, we have increased the response buffer size by adding a <%@ page buffer="nK" %> header to our JSPs and a response.setBufferSize call to our Servlets. The responses still do not contain a content-length header.
Is there anything else we can do to get WebLogic to set this header?
Thanks in advance,
Santosh

Anybody?

Unable to deserialize HTTP response content - SharePoint Designer Call Web Service Workflow Activity

I am creating a workflow using SharePoint Designer 2013 and I'm using the call HTTP web service action.
The web service call works (it is for a text messaging service, and I get the text message to my phone) however the workflow stops at this point with internal status "suspended" and gives the error message below when clicking on the "i"
icon.
I have tried setting the Accept and Content-Type request headers to "application/json; odata=verbose" (minus the quote marks) as other posts suggested but this doesn't make a difference (e.g. here: https://social.msdn.microsoft.com/Forums/windowsapps/en-US/f0b18411-87d1-466b-aab0-1a0093605ed4/workflow-cannot-read-json-after-latest-sp15-patches?forum=sharepointdevelopment).
I tried adding in the Content-Length header too but that made no difference.
I tested calling another web service (https://sharepointurl/_api/contextinfo) and this works fine.
Is there any way to get the workflow to accept this XML as the response? I don't actually really need anything out of the response content, but I do need the workflow to carry on after this step and carry out other activities after this call.
Error message:
Details: An unhandled exception occurred during the execution of the workflow instance. Exception details: System.IO.InvalidDataException:

Content-length in HTTP Post request

Hi all,
I have a problem with a Http request. I send data in a POST to a servlet, but the KVM doesn't set the Content-Length correctly. How can I do ?
The code :
conn = (HttpConnection) Connector.open(m_strServer);
conn.setRequestMethod(HttpConnection.POST);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
String requestData = "from=" + m_strOriginator + "&to=" + m_strDestinator + "&message=" + m_strMessage;
out = conn.openDataOutputStream();
out.write(requestData.getBytes());
out.flush();
in = conn.openDataInputStream();
if (conn.getResponseCode() == 200)
response = true;the request sended :
POST /my_directory/test.xml HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Transfer-Encoding: chunked
Host: my_pc
15
from=8&to=9&message=J
0
I think that the KVM doesn't put "Content-Length:" before "15".
Perhaps it's a bug.
St�phane

Maby u try to force it with:
conn.setRequestProperty ( "Content-Length" ,
Integer.toString (requestData.getBytes()));
for me it does also not work...but u never know
lemme know if it works

OATS Enhancement: Verify the response contents of http requests which enclosed by begin/endconcurrent

Recently I’m testing the Fluid UI with OATS 12.4.0.2.
In this test, since the browser get all tiles in current page simultaneously, I have to simulate this behavior in OpenScript/OLT.
Then I put all those http requests into a concurrent block ( marked by begin/endconcurrent statments) and it works fine.
But this bring in a limitation: so far, the OATS doesn’t support to verify the http response contents if those http requests resided inside the concurrent blocks.
So I did an enhancement for OpenScript to overcome this limitation. I think it might useful if you have similar test scenario.
How to use it:
Put the attached file ConcurrentHTTPService.java into your OpenScript project folder ( same folder as where your script.java living).
Replace the alias line for http in script.java, the below is after replacement:
//@ScriptService oracle.oats.scripting.modules.http.api.HTTPService http;
@ScriptService ConcurrentHTTPService http;
3. Put your http.get inside concurrent block as usual:
http.beginConcurrent("Get_Tiles_Concurrently");
//The below IDs are useful for later. We use this ID to identified the http requests inside the concurrent block.
//If you dn’t have those IDs, it’s OK, we can use the full URL string (including all parameters)to do the same thing,
//but the full URL is very long, and I hate the screen were occupied by URLs…
http.get( 193, "http://Page1",...);
http.get( 194, "http://Page2",...);
http.endConcurrent("Get_Tiles_Concurrently");
4. After endConcurrent statement, We can use the following methods to get the http response content by RecID or full URL:
//Those methods should be used after the endConcurrent statement
//Get the response contents:
//Please reference the http.getLastResponseContent method for the explain of parameters.
info("Resp 193/Page1:" + http.getLastResponseContentForConcurrent(193,Source.Html));
info("Resp 193/Page1:" + http.getLastResponseContentForConcurrent("http://Page1",Source.Html));
//Verify the response contents:
//Please reference the http.AssertText method for the explain of parameters.
http.AssertTextForConcurrent(193, "Text Match Name", "Key_word_should_appear_in_response_content_of_request_193/page1",
Source.Html, TextPresence.PassIfPresent, MatchOption.Exact);
http.AssertTextForConcurrent(("http://Page1", "Text Match Name", "Key_word_should_appear_in_response_content_of_request_194/page2",
Source.Html, TextPresence.PassIfPresent, MatchOption.Exact);
Done!
Thank glenn.s in this thread: How to test asynchronous web service.

I think I have the solution to your dynamic addressing problem, but I have a problem combining HTTP authentication with dynamic address resolution.
I've got an external service that requires basic authentication and I've handled it successfully by adding a <MustSupportBasicAuthentication> block to the WSDL, as described in the article "Basic Authentication in HTTP SOAP BC" (http://wiki.open-esb.java.net/Wiki.jsp?page=HTTPBasicAuthentication). This works perfectly, causing the HTTP BC to send credentials every time it accesses the external service.
Now I want to make the URL of this external service dynamic (i.e., read it at run time from a configuration mbean). I followed the example from the article "Using Dynamic Address feature" (http://wiki.open-esb.java.net/Wiki.jsp?page=UsingDynamicPartnerLinks), which shows you how to send an endpoint reference (EPR), in the form of an <EndpointReference> block. This also works fine.
(I believe this last technique is the solution to your dynamic addressing problem. I've used both with and without BPEL. To use it outside of BPEL, you make a DocumentFragment out of the XML tree that begins with <EndpointReference> and pass it as an argument to the resolveEndpointReference method of your component context. This causes the JBI container to contact the HTTP BC, which understands the EPR.)
My problem is this: once I've dynamically changed the target URL of the external service, the HTTP BC seems to forget that it requires authentication and no longer sends credentials.
Has anyone else experienced this behavior, and if so how did you work around it?

Gzip / Content-Length HTTP-Header

Hello,
I'm writing an HTTP-Proxyserver, but I don't know how to get the length of a GZIPOutputStream ... I'm compressing the data, if the server does not send gzipped data:
logger.debug("Encode as GZip data!");
byte[] BinaryBody = new byte[8192];
GZIPOutputStream gzipOut = new GZIPOutputStream(client.getOutputStream());
int length;
while ((length = in.read(BinaryBody)) != -1)
gzipOut.write(BinaryBody, 0, length);
gzipOut.flush();
gzipOut.close();I often get a Nullpointer exception in the line (while ((length = in.read(BinaryBody)) != -1)
I think it's because I don't set the Content-Length Header, but I'm not sure.
greetings,
Johannes

Disable the "Use Chunked Streaming Mode" property in HTTP Transport Configuration of your business service. By default it remains enabled.

OSB - Content length http header missing from business service out message

Hi all,
I am having some diffuclty with a business service in OSB. I created the business service from the wsdl and created a regular proxy service that just routes to the business service. When i run the test console i get the below fault.
<faultcode>soapenv:Server</faultcode>
<faultstring>BEA-380000: Length Required</faultstring>
<detail>
After some debugging i find that the content length http header is missing from the outbound message the business process creates and sends to the acutal web service which sends back the http 411 fault.
Does anyone know how to configure the message flow of my proxy service to ensure that the outbound message sent from the business service contains that content length http header or any suggestions on how to fix this issue will be appreciated.
Thanks

How to verfiy the http compression

Hi, I'm using Sun ONE Web Server 6.1, and have configured it to compress the content on demand.
I received the following http response, but in both cases of turning on/off the compression on demand.
HTTP/1.1 200 OK
Server: Sun-ONE-Web-Server/6.1
Date: Thu, 13 Jan 2005 09:36:29 GMT
Content-Type: text/html
Transfer-encoding: chunkedHow can I verify the compression work?
Will it show different result in case of turn on/off the compression?
TIA,
Matthew

Sorry about that. Because you pasted in an HTTP response, I assumed you already knew how to manually submit HTTP requests.
You can use telnet to submit HTTP requests, impersonating a web browser. Here's an example on a Solaris machine, mbelshe, where I have a Web Server instance running on port 2600:    elving@mbelshe:~> telnet mbelshe 2600
    Trying 10.5.80.146...
    Connected to mbelshe.
    Escape character is '^]'.
    GET / HTTP/1.0
    HTTP/1.1 200 OK
    Server: Sun-Java-System-Web-Server/7.0

    elving@mbelshe:~> The stuff in bold is the stuff I typed. I'll try that same HTTP request again, but this time indicate that I want a compressed response:    elving@mbelshe:~> telnet mbelshe 2600

    Connected to mbelshe.

    elving@mbelshe:~> Note that when I ask for a compressed response, the server responds with a Content-encoding: gzip header and spews out gobbledygook instead of HTML.
There are other, prettier ways to get this sort of information. One such way is the LiveHTTPHeaders extension for Mozilla and Firefox. There's more information on that extension at http://livehttpheaders.mozdev.org/.
