We configured SSL successfully and run it for couple of weeks,
We disable the SSL using script mentioned 1364368.1
It should not redirect to https, but work as it is.
1. What is http://server.domain.com:8000/ ? Is this a Load balancer or Proxy server ? Were you using SSL termination ?
2. After making the changes to disable SSL, you ran autoconfig and restarted all eBiz middle tier services ?
3. Take a look at "Step 8 - Update the Context File" in "Enabling SSL in Oracle E-Business Suite Release 12" (Doc ID 376700.1) and make sure your $CONTEXT_FILE has all the correct values listed under "Non-SSL Value"
Thanks for your reply.
I found the problem, every thing was OK.
The problem was with IE8, new feature of using same session for multiple visits to same site.
I just use new session , it was working.
Thanks for the update and for sharing the solution.
