'string tolower $my_string' returns the $my_string value in lower case. It's used primarily for doing case insensitive comparisons. HTTP paths in IIS are not case sensitive. Host names should always be treated as case insensitive for any application platform. I assume with servlets that you're not on an IIS platform. If you're on a Java based platform, you should be able to leave the case alone and use a case sensitive comparison.

 

 

If you have 'port translation' enabled on the virtual server properties, LTM will translate the destination port from the virtual server port to the pool member port. This is enabled by default on all but port 0 (any) virtual servers.
