Hello Amol, first some formalities:
1) Please do not cross-post the same message to different mailing lists. The discussions in the mailing lists will drift apart, and everyone who is not subscribed to all lists will not get the full picture. 2) Please post plain text mails, not HTML mails. 3) Large attachments will be removed by the mailing list server. now to the technical part: Your proxy implementation is defective. In particular, you are sending a Content-Length header of 46, but a message body with 48 bytes. Please check the relevant sections of RFC 2616. Some headers must be passed on by a proxy, others removed, and some need to be adjusted depending on what the proxy does. In your particular case, don't set the Content-Length header nor the Transfer-Encoding header. HttpClient will take care of such things. If you create a new connection manager, you effectively disable connection re-use. The problem is that the server stops reading the message body after 46 bytes, but you send 48. If the connection is re-used, the two additional bytes will be considered part of the next HTTP message, with the result you witnessed. If the connection is not re-used, the two bytes will just be missing from the data that the server receives. Either way, your proxy is broken. hope that helps, Roland "Amol Kulkarni" <[EMAIL PROTECTED]> 16.06.2005 12:33 Please respond to "HttpClient Project" To <[email protected]> cc <[email protected]> Subject Problem with HttpConnectionManager Hi , I am using HttpClient as a Proxy Recorder i.e. An request made through Browser goes through my code and I am using HttpClient to fire the browser request. The response that I get from HttpMethod is written back to the Browser. I facing a problem (which I feel is a bug in HttpClient). To test my Proxy Recorder I have configured the PetStore demo. Very briefly, The first URL that I fire (or execute using HttpClient) is http://localhost:8080/petstore/signon_welcome.screen [DEBUG] header - >> "GET /petstore/signon_welcome.screen HTTP/1.1[\r][\n]" [DEBUG] HttpMethodBase - Adding Host request header [DEBUG] header - >> "Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, */*[\r][\n]" [DEBUG] header - >> "Accept-Language: en-us[\r][\n]" [DEBUG] header - >> "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.0.3705; .NET CLR 1.1.4322)[\r][\n]" [DEBUG] header - >> "Proxy-Connection: Keep-Alive[\r][\n]" [DEBUG] header - >> "Host: localhost:8080[\r][\n]" [DEBUG] header - >> "[\r][\n]" [DEBUG] header - << "HTTP/1.1 200 OK[\r][\n]" [DEBUG] header - << "Set-Cookie: JSESSIONID=E3EC131BD85879A0BAF747C2AF373DED; Path=/petstore[\r][\n]" [DEBUG] header - << "Content-Type: text/html;charset=UTF-8[\r][\n]" [DEBUG] header - << "Transfer-Encoding: chunked[\r][\n]" [DEBUG] header - << "Date: Thu, 16 Jun 2005 09:55:19 GMT[\r][\n]" [DEBUG] header - << "Server: Apache-Coyote/1.1[\r][\n]" The response is a form which has 2 forms, one for Signing in and another for registering a New User.

The expected behaviour is that the user logs in to the Store, But On submitting this request, I get "HTTP Status 501 - Method InGET is not defined in RFC 2068 and is not supported by the Servlet API " Note the Method "InGet", The "In" is actually value of the last parameter sent in the Post Method. [DEBUG] content - >> "j_username=j2ee&j_password=j2ee&submit=Sign%2BIn" I have checked this with some other Post method submits in the Petstore demo itself, And I am getting end characters of the Post method's request data. I am attaching the trace.log file with this mail. Note that I am handling the Redirection in my code, hence I have set the redirection to false. I have performed the "Things To Try", and this happens only when my code sits between Browser and server. I have debugged the problem, And If I create the MultiThreadedHttpConnectionManager every time I create an object of HttpMethod and set it to HttpClient's reference, this problem doesn't arise i.e. The response on submitting the form is proper one. I know that MultiThreadedHttpConnectionManager should not be created every time. Please let me know If I am doing something wrong or is this a bug in HttpClient's code? I have also tried this with the nighty build. My code is also based on the tutorial i.e. the sequence of API's being called are in the same sequence. Eagerly waiting for your response.
