HTML form submits and the hostname changes to IP address

I am facing a peculiar proble开发者_JAVA百科m. The problem is, my webapp is being installed behind a proxy. The request gets submitted to the proxy which forwards the request to the original host that is running the websphere web application. The problem I am facing is, when I access the webapp, its URL looks like the below

http://www.myproxy.com

Lets say I get a form on this URL, when I submit the form, it is getting submitted to another URL - http://10.1.2.87

Since the URL is changing, application server thinks it is a different session and throws the login page again. The login page comes thru a filter which checks whether user is already authenticated in the session or not. I do not have much knowledge on proxy settings .. where do you think is the problem?

Thus, you're using a reverse proxy. You need to configure it to manage the sessions as well. To the point, it should send the HTTP Cookie and Set-Cookie headers forth and back as well. Consult the documentation of the proxy in question for details or ask at serverfault.com for detailed assistance (don't forget to mention which proxy you're using).
