Netscaler Knowledgebase

I'm using NetScaler in DMZ as reverse proxy for several web applications.
Everything works fine:

• user from the Internet go to https://app01.domain.com,
• it redirect user to https://auth.domain.com,
• user enters credentals that are then validated on LDAP,
• NetScaler redirect user to web application

Configuration is little bit more complex because I'm using single public IP to publish multiple sites using content switch.

The problem is when user bookmarks authorization page.
When user goes back, NetScaler authenticate user and then it reports error "Http/1.1 Internal Server Error 29"

Is there a way to prevent this?

Thanks for your help,
Vojin

It's POST

Page get's redirected to:
https://auth.site.com/cgi/login

Authorization process shows normal steps
