NimbostratusPersistence Issue on LTM
Please advise if possible Issue:
Intermittent ASP.NET times-outs occurring intermittently when accessing an ASP.NET based application when using a pool of load balanced servers with the HTTP Cookie Insert option selected for persistence. No issues occur when using single pool member.
The back-end application is running IIS 8.5 Server log error is:
2020-04-01 11:21:13 10.71.244.57 POST /AthenaCustody/Pages/AjaxMethods.aspx/LogJavascriptError - 80 - 10.71.244.1 Mozilla/5.0+(Windows+NT+10.0;+Win64;+x64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/80.0.3987.122+Safari/537.36 http://ppfeglcnaweb01/AthenaCustody/Pages/Arrest.aspx?CustodyRecordId=0 500 0 0 0

You need to check the pool member logs to see if that particular session was originally established on another IIS server (probably by tracking the ASP.Net session ID).
You might want to manage the persistence using
K7392: Overview of universal persistence
based on something like an ASP.Net session ID.
AkeemThanks for the information, I'll investigate your advice and feedback.

Still investigating the issue.
I can confirm that when the customer uses the Single-Sign-On URL (https://connect-ppf-full) there are no issues
However they also use another method called: MockIAM route (http://ppfeglxxxweb01/gemlogin/mockIAM.jsp) , which uses a ReverseByPasss proxy file.
We have an issue with this method I've gathered some TCPDUMPs that we're currently analyzing. Will let you know what the outcome is.
