Cookie persistance

Hi Team,

 

We noticed a strange issue in our Enviornment.

 

Currently we enabled the default persistence as cookie. When we tried to access the application from different browser all the request are sending to only App server. Pasting below the jsession ID and cookie information. i could see the cookie information is same for all browser, Why it so? Finally I want to know when F5 will send the request to second APP server, does it require clearing cache on browser or F5 cookie?

 

IE:

 

mda_JSESSIONID=mOKmvioojyuMCkbprmyd698G; BIGipServerSAAS_MDA_POOL=3730919434.63530.0000

 

Chrome:

 

mda_JSESSIONID=YU4G9p8bcy0ZAZCL1KQA0cI3; BIGipServerSAAS_MDA_POOL=3730919434.63530.0000

 

Firefox:

 

BIGipServerSAAS_MDA_POOL=3730919434.63530.0000; mda_JSESSIONID=0Ddk1aKwg1CMNMXBlt-oMiiW

 

Thanks,

 

Akhi

    Please make a test without any persistance profile on your pool in order to check if Round Robin LB methods works.

     

    Please provide "list ltm virtual"
