Persistence across VS with different Poolmembers

From the logging we could verify that both lookups didn't find a match in the session table although the second request should find the entry of the first request.i have never come across this situation but i think it may be possible if two requests come really really close.

 

 

by the way, are all 4 websites in the same domain name (different subdomain)? if yes, would it be possible to configure static cookie on pools? so, first request will be load balanced and later will be directed to pool member based on static cookie value.

 

 

or am i totally lost what you are asking? :-)
