class match hostname in 10.2.1 irule

Guys,

 

 

My website www.mycomp.com also has some country specific domain registration addresses. Customers visiting my website on a regional address need to be routed to my .com address and get my website shown.

 

 

IMHO, most decent way to do this is to use a data group for this, put in the country specific domain names and match the domain name request against the data group entries and do a redirect.

 

 

Implementation:

 

 

I've created a string type data group named "website_aliases"

 

Filled it with string/values equal to domainname/pool (pool is not used as an reference but each string needs a value), a couple of examples:

 

www.mycomp.de pool_mycomp

 

www.mycomp.fr pool_mycomp

 

www.mycomp.nl pool_mycomp

 

 

The in the irule:

 

 

when HTTP_REQUEST {

 

set host [string tolower [HTTP::host]]

 

set uri [string tolower [HTTP::uri]]

 

 

switch -exact $host {

 

"www.mycomp.com" {

 

pool pool_mycomp

 

}

 

if {[class match $host equals website_aliases]} {

 

HTTP::redirect http://www.mycomp.com/ }

 

}

 

}

 

 

Irule is accepted so contains no syntax errors.

 

Still after synch, when trying in a browser http://www.mycomp.com , it is reinitialised

 

Any of the aliases also don't work either so https://www.mycomp.de is not redirected to http://www.mycomp.com

 

 

Any ideas?

    Hmm, in you're rule you specify an "--" in the class match, why is that?:

     

    if { [class match -- [HTTP::host] equals website_aliases] }

     

     

    Furthermore interesting that you're setup works...

     

     

    Thnx,

     

    Michiel

    your irule is not working since you are not able to mix switch with if-clause likes that.

     

     

    hope this helps.
