Subject RE: Cookie problem with strict mode
Date Tue, 06 May 2003 07:23:22 GMT
2.0-alpha3 release is known to have a few issues. Once of those issues is cookie duplication
when requests are retried multiple times due to a redirect or authentication failure. Just
upgrade to the most recent nightly build and the problem should go away

http://jakarta.apache.org/commons/httpclient/downloads.html

If the problem persists after the upgrade, please follow the HttpClient trouble shooting guide
and get back to me with the wire log that demonstrates the problem

http://jakarta.apache.org/commons/httpclient/troubleshooting.html

Cheers

Oleg

Subject: Cookie problem with strict mode


Hi,
i am using httpclient2.0alpha3 to make queries to the pubmed site. The
site expects multiple cookies to be appended by a semi-colon. So i have
set strict mode to tru to enable the feature. But then the addition of
cookies behave in a strange way. Below, is the log from a proxy through
which the requests were sent -

As you can see two cookies were received. Now, notice how the cookies
are sent when consecutive queries are made.

The same cookies are sent twice. But when i make the second query, this
time with page=2, notice how the problem dissapears.
I have tried all the cookie policies. NETSCAPE_DRAFT and COMPATIBILTIY
give the same result. The other one rejects the cookies. I tried the
same thing with a browser, it was working fine. Can anyone please help
me with this problem.
