iRules Pool Selection

The other thing I noticed is that your if's are not chained. Eg, it's not "if { expr } { body } elseif { expr } { body }"

 

 

So, if you happen to encounter a uri that contains both "iruleuri" and "aspnet_client" then the latter pool will always be used, though you might be expecting the former. You could test that by simply changing the second "if" to an "elseif" (and make sure there is either no whitespace either before the "elseif" or on the end of the preceding "}" line OR combine the "elseif" onto the preceding line).
