dev servers irule

hey guys,

 

not sure how to do this one, I have

 

dev01.www.etc.com, dev02.www.etc.com, through dev20.www.etc.com

 

I also have

 

dev01.app.etc.com through dev20.app.etc.com.

 

 

I want to make an irule that forwards a URI from www to app.

 

when HTTP_REQUEST {

 

if { [string tolower [HTTP::uri]] eq "/production/webservice.asmx" } {

 

HTTP::redirect "http://dev16.app.etc.com/webservice.asmx"

 

}

 

}

 

I have this on the dev--.www.etc.com VS, I have one VS for all DEV01-20 and use an irule for node redirect based on what DEV they are calling. but as you see it is only forwarding to dev16.

 

if it hits dev05.www I wanted it to forward to the dev05.app

 

application delivery
dev
devops
iRules

    OK, I'm no expert and haven't used findstr much or had to use variables with redirect but here's my first attempt. The idea is to check for a request containing www, pull out the server number and redirect to the correct app domain/server; 

    
when HTTP_REQUEST {
 if { [string tolower [HTTP::host]] contains ".www." } {
  set devserverid [findstr [HTTP::host] "dev" 0 "."]
  log local0. "Found $devserverid in HTTP host"
  HTTP::redirect "http://dev" + "$devsererid" + ".app.etc.com[[http:uri]]"
  }
}

    Nice I tweeked it a bit, but the core was solid.

     

     

    when HTTP_REQUEST {

     

    if { ([string tolower [HTTP::host]] contains ".www." )

     

    and ([string tolower [HTTP::uri]] eq "/webapiproduction/webservice.asmx") } {

     

    set devserverid [findstr [HTTP::host] "dev" 0 "."]

     

    HTTP::redirect "http://$devserverid.app.etc.com/webservice.asmx"

     

    }

     

    }

     

     

    This works for all Dev01-20, listening for www and the /webapiproduction/webservice.asmx then sending them to dev01-20.app.etc.com/webservice.asmx

     

     

    Thanks for all the help
