REGEX Alternatives

I've been trying to figure out how i'd structure a particular portion of my iRule to look for values contained in a string, instead of a regular expression but i'm having some difficulty:     Th...

Aaron,

 

 

That worked beautifully! I have one more question regarding REGEX alternatives as it relates to the iRule i'm working on.

 

 

Is there a more efficient method to do the following, versus the REGEX i'm currently using?

 

 

when HTTP_RESPONSE_DATA {

 

 

Check for the FQDN of domain oasis.local in the payload

 

regexp {GMVM(\d)+\.oasis\.local} [HTTP::payload] found

 

 

if {$found != -1 } {

 

Insert a new cookie with the old host IP name and old cookie's value

 

HTTP::cookie insert name "DRCShared_IP" value $found domain "example.com" path "/"

 

 

Replace embedded URL to Oasis Host with URL to VIP of abc.example.com

 

STREAM::expression {@GMVM(\d)+\.oasis\.local@abc.example.com@}

 

STREAM::enable

 

}

 

}

 

 

I'm having a bit of difficulty wrapping my head around when i can use regular expression rules to match on items using strings instead.
