we are running EP60 sp13; when we get to the portal via IIS (SSO), after a short period of work, the Portal doesn't work anymore.
We are always redirected to the home page (sometimes a blank page).
Everything returns all right when rebooting the portal machine.
I don't have this problem when going through 50000 port.
I have already had a look to SAP notes, and what I did is:
-downgrade iisproxy.dll to 1.6.1 version
-set the parameter UrlSegmentMaxLength in the registry at the maximum allowed.
But this doesn't solve our problem, after some hours the portal doesn't work anymore.
Does anyone of you have any idea about this?
Thanks in advance
