Refesh Button Issue !1!
Hi,
I have written an application that uses Httpclient to automatic login into other Applications
and display the home page on the browser.
Some of the other applications use GET and some use POST for login .
For an application that uses POST for login I face a strange issue.
When I press the refresh button on the home page after login(accessing thru my application)
It shows me the login screen !!!!
I investigated further and found out this
When I tried accessing the application directly by going to login screen and then entering username
and password and then going to the home page
Then when I press the Refresh Button, I get a POP up which says that u are trying to resubmit the
information do u want to continue(Something like this)
When I say yes, I again reach the home page as the login details are submitted again
This happens because the browser knows that it was a POST request !!!!
When I access the application thru my code it is a get request so the browser does not try to resend the data and hence
I am shown the login screen .
Is there is a workaround possible ? Please help me
Regards,

Subject: ant file for converting src from commons-logging to log4j for
2.0.1
Attached is an ant build file that can be plopped into your basedir for
httpclient. (I tested it with the 2.0.1 src distro rather than a cvs
dir.)
% ant -buildfile commons-logging-to-log4j.xml -projecthelp
Buildfile: commons-logging-to-log4j.xml
Main targets:
convert convert source from commons-logging to
log4j apis
install-log4j-properties copy log4j properties to classes dir
make-src-backup make src.orig directory
revert Put original java source code back
uninstall-log4j-properties remove log4j properties from classes dir
With some massaging, these targets could probably be renamed and merged
into build.xml and maintained there (and probably belong there). Also,
in my envirionment, I used a build.properties that has
${commons-logging.jar} pointing to a copy of log4j.jar. If I were going
to maintain this inside the commons-httpclient/build.*, I'd rename the
commons-logging.jar property to ${logging-jar}, too, so things would
make a little more sense.
I ran the tests and it seems to basically work. I can now, happily say
'bubbye' to commons-logging.
Enjoy

Manish,
Are you writing some kind of 'proxy' like in the image below?
Browser <----> your proxy <----> the webapp requiring authentication
A webapp needs to keep track of a user in the user session (internal
state). HTTP provides the cookie mechanism to enable webapps to match a
session with a request. If you proxy the communication to a webapp you
must be able to provide the right session cookie to the application.
That means that your proxy needs to establish both, a session with the
webapp and a session with the client and do the translation between the
two. Please note, that cookies are subject to security restrictions. A
cookie can only be set and read by the same host(domain). This means
that you have to proxy *all* communication between the client and the
webapp. You can not only perform the login by the proxy and then access
the webapp directly from the client bypassing the proxy. This also means
that you need to do URL rewriting in all the HTML code so that your
proxy is used.
