something interesting in if {if } else

irule

 

if {($uri matches "/cjj" or $uri matches "/cjj/") } {

 

if { [HTTP::host] ends_with ".co.uk" } {

 

HTTP::redirect "http://[HTTP::host]/error.html"

 

return

 

}

 

}

 

else {

 

pool xxxx

 

}

 

 

http://www.ss.com/cjj doesn't hit pool xxxx,why?

 

 

this url doesn't match ".co.uk",why irule doesn't pass it to else?
  • Hi Jucao,

    www.ss.com/cjj would match the first if but not the second. So it wouldn't hit the pool statement. If you want to use that pool for www.ss.com/cjj, you could try this:

    
    if {($uri matches "/cjj" or $uri matches "/cjj/") } {
    if { [HTTP::host] ends_with ".co.uk" } { 
    HTTP::redirect "http://[HTTP::host]/error.html" 
    return 
    } else {
    pool xxxx
    }
    } else {
    pool xxxx
    }

  • ok,I see

     

    once /cjj is matched,but no action is in irule,F5 will send fallback host(fallback host is configured) to client,right?
