Simple match of URL based on regular expression

Hi there,

A string comparison would be more efficient than a regex. If you really want to check if the postcode and email parameters are in the URI in a particular order you could use [string match *postcode=*email=* [HTTP::query]] to perform the test. Else if you want to check if the query string contains the two parameters in any order you could do two checks ([string match *postcode=*email=* [HTTP::query]] or [string match *email=*postcode=* [HTTP::query]]) or parse the parameters using URI::query (Click here)

Here is the first option:

  
  when HTTP_REQUEST {  
    
      Check if the query string contains anything postcode anything email anything or anything email anything postcode  
     if {([string match *postcode=*email=* [HTTP::query]] or [string match *email=*postcode=* [HTTP::query]])}{  
    
         Query string matched, so use PoolB  
        pool PoolB  
    
      } else {  
    
         Query string did not match, so use PoolA  
        pool PoolA  
     }  
  }  
  

Here is the second option which parses the query string for the actual parameter values and checks if they have a length. If you don't care whether the parameters have a value, you can remove the string length check on the values:

  
  when HTTP_REQUEST {  
    
      Check if the query string contains the postcode and email email parameters with lengths  
     if {([string length [URI::query [HTTP::query] postcode]] and [string length [URI::query [HTTP::query] email]])}{  
    
         Query string matched, so use PoolB  
        pool PoolB  
    
      } else {  
    
         Query string did not match, so use PoolA  
        pool PoolA  
     }  
  }

So after some persistance I got this one to work. I hope its doing the correct thing, but initial testing looks OK.

 

 

 

 

when HTTP_REQUEST {

 

 

if {[HTTP::uri] matches_regex "(.*)?postcode=(.*)&email=(.*)"} {

 

log "Landing pages on Pool B"

 

pool uSwitchPoolB

 

} else {

 

 

}

 

}

Thanks Hoolio

 

 

Im going to try your suggestion now!
