redirect issue with httpclient
hi all,
I am using Jakarta HTTPClient to do a post on a website.
it seems that after the authentication the page is getting redirected to
other location.
the significant thing is that its changing the port also.
below i am posting the output i am getting from my code.

how can i make httpclient to get redirected to the new location
automatically.
here is my code:

RE: redirect issue with httpclient
Himanshu,
HttpClient 2.0, unfortunately, cannot automatically handle cross-host redirects. But
this limitation is not difficult to work around. See the document below
http://jakarta.apache.org/commons/httpclient/redirects.html
HttpClient 3.0 will address this limitation
Oleg

Use the logging features to see exactly what was sent back (and make sure you're cookies are in compatibility mode).

Re: Redirect Issue
Hi again Sunil, I'm doing too many things at once here so I could be wrong, but would http://nagoya.apache.org/bugzilla/show_bug.cgi?id=20240 be the same problem you're having? If so, you should be able to upgrade to the latest nightly build and the problem would be fixed. I can't be sure if the fix made it into beta 1 or not - it's definitely worth a look anyway. Otherwise I promise to shutup and let Oleg impart his wisdom. :) Adrian.

RE: Redirect Issue
Sunil, 'Set-Cookie: DOMS=; PATH=' cookie is rejected as it violates the RFC2109 specification. Here's what you should do to work the problem around: 1) Upgrade to the latest nightly build (commons-httpclient-20030527.tar.gz) http://cvs.apache.org/builds/jakarta-commons/nightly/commons-httpclient/ 2) Use compatibility cookie policy. See examples below http://cvs.apache.org/viewcvs/jakarta-commons/httpclient/src/examples/CookieDemoApp.java?rev=HEADcontent-type=text/vnd.viewcvs-markup That should help Cheers Oleg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Redirect Issue
Hi, I think I should explain you the problem at hand clearly. Users come to our site A and provide some information on page N. Our application should process the information and depending on the user should send POST data to other URLs. Those URLs are supposed to receive dat and display their page back. So users are being redirected to diff site page. I'm using httpclient to send POST message. Should I need to get the response back and display it OR sending POST message is enough and browser will get new page from site B.
