Web based URL hosted in F5 is getting logged off often while user working in it

I have public domain called https://abc.com I have hosted three application under this abc.com domain includes https://abc.com/def, https://abc.com/ghi and https://abc.com/jkl

These application use three different pool members namely as below https://abc.com/def- def_pool https://abc.com/ghi - ghi_pool https://abc.com/jkl - jkl_pool

I have three different http cookie persistence for three pools - def_pool- def_http_cookie - Expiration is set to 1day ghi_pool- ghi_http_cookie -Expiration is set to 1day jkl_pool- jkl_http_cookie- Expiration is set to 1day

VIP configuration follows VIP - abc.com , I have done following configuration under this VIP I have mapped default pool as jkl_pool and default persistence as jkl_http_cookie . Remaining application I called in the i-Rule and i-Rule configuration follows

when HTTP_REQUEST { if { [HTTP::uri] contains "def" } { pool def_pool persist cookie insert def_http_cookie

Testing : 1) with above configuration - URL https://abc.com/jkl works fine, URLs https://abc.com/def, https://abc.com/ghi are facing with logged off issue often while user working on these URLs 2) I removed the i-Rule configuration and configure these URLs https://abc.com/def, https://abc.com/ghi with default pool members and default persistence profile Individually one by one and tested and I did not face log off issue.

So I guess when I have i-Rule configuration with persistence setting and its not working as expected. I think , it makes clear point to you now. please suggest your views
