HTTP to HTTPS and Back

I tested the rule, the one that combines the HTTP and HTTPS logic, and it works perfect. However, I used the "contains" rather than the "starts_with" relational operator considering the fact that the URI will not necessarily start with the path but the class path can be deeper in the URI string.

 

 

Is there any particular benefit to using "starts_with" rather than the "contains" relational operator?

 

 

And one final question...

 

 

From performance and optimization point of view...is it better to use one iRule combining the forward and reverse logic for the HTTP and HTTPS virtual server, and assign it to both virtual servers, or is it better if the iRule is split in half and the forward logic is assigned to the HTTP virtual server and the reverse to the HTTPS virtual server?

 

 

Thanks for your support.
