issue with irule script ???

This one works fine.

 

when HTTP_REQUEST {

 

if { [string tolower [HTTP::uri]] contains "/secure_one" } {

 

set replaceURI [string map [list /secure /wrap1] [HTTP::uri]]

 

HTTP::redirect "$replaceURI"

 

}

 

elseif { [HTTP::uri] contains "/one" } {

 

HTTP::redirect "" }

 

}

 

 

But the following doesn't work fine. why ?

 

 

when HTTP_REQUEST {

 

 

if {{ [string tolower [HTTP::uri]] contains "/secure_one" } {

 

set replaceURI [string map [list /secure_one /wrap1] [HTTP::uri]]

 

HTTP::redirect "$replaceURI"

 

}

 

 

elseif { [HTTP::uri] contains "/one" } {

 

HTTP::redirect "http://www111.abc.com[HTTP::uri]" }

 

}

 

 

if {{ [string tolower [HTTP::uri]] contains "/ask_wrap" } {

 

set replaceURI [string map [list /ask_wrap /wrap1] [HTTP::uri]]

 

HTTP::redirect "$replaceURI"

 

}

 

 

elseif { [HTTP::uri] contains "/wrap" } {

 

HTTP::redirect "http://www111.abc.com[HTTP::uri]" }

 

}

 

 

 

if {{ [string tolower [HTTP::uri]] contains "/seek_pond" } {

 

set replaceURI [string map [list /pond /wrap1] [HTTP::uri]]

 

HTTP::redirect "$replaceURI"

 

}

 

 

elseif { [HTTP::uri] contains "/seek" } {

 

HTTP::redirect "http://www111.abc.com[HTTP::uri]" }

 

 

}}

 

no luck with this... have been trying for sometime....

    You seem to have too many braces in there with each if statement (two instead of one) and I would also suggest you put a line break between the last two as well. Note you could improve the rule by only having the first if and everything else being an elseif. Also, I'd say using the string operator would be far better than using this many if, elseif statements. This doesn't quite cover all your requirements but gives you the idea; 

    
when HTTP_REQUEST {
 switch -glob [string tolower [HTTP::uri]] {
  "/wrap*" -
  "/seek*" -
  "/one*" {
   HTTP::redirect "http://www111.abc.com[HTTP::uri]"
    }
  "/secure_one*" - 
  "/seek_pond*" -
  "/ask_wrap*" {
   HTTP::redirect "$replaceURI"
  }
 }
}

    Hi

     

    Thanks for the reply, just want to clarify the requirement.

     

     

    when we try for any of the URL, a part of URI needs to be changed to wrap1 and rest of the URI should be same. pls note this has both URL redirection with URI parsing too.

     

     

    http://www111.abc.com/secure_one/anythinghere/image.gif

     

    http://www111.abc.com/ask_wrap/anythinghere/anythinghere/image.gif

     

    http://www111.abc.com/seek_pond/anythinghere/anythinghere/image.gif

     

     

    should redirect to

     

     

    http://www245.abc.com/wrap1/rest of old uri

    I'm sure it could be improved but for now this will do and is still far better; 

    
when HTTP_REQUEST {
 switch -glob [string tolower [HTTP::uri]] {
  "/wrap*" -
  "/seek*" -
  "/one*" {
   HTTP::redirect "http://www111.abc.com[HTTP::uri]"
    }
  "/secure_one*" {
   set replaceURI [string map [list /secure_one /wrap1] [HTTP::uri]]
   HTTP::redirect "$replaceURI"
  "/seek_pond*" {
   HTTP::redirect "$replaceURI"
   set replaceURI [string map [list /seek_pond /wrap1] [HTTP::uri]]
  "/ask_wrap*" {
   set replaceURI [string map [list /ask_wrap /wrap1] [HTTP::uri]]
   HTTP::redirect "$replaceURI"
  }
 }
}

    just another example. 

    [root@ve10:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.252:80
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
  if { [HTTP::host] equals "www111.abc.com" } {
    switch -glob [HTTP::path] {
      "/secure_one/*" -
      "/ask_wrap/*" -
      "/seek_pond/*" {
        HTTP::redirect "http://www245.abc.com[string map {/secure_one/ /wrap1/ /ask_wrap/ /wrap1/ /seek_pond/ /wrap1/} [HTTP::uri]]"
      }
    }
  }
}

    Thanks for the feedback. Here's a corrected version of my rule above just for reference (which was missing quite a few braces); 

    
when HTTP_REQUEST {
 switch -glob [string tolower [HTTP::uri]] {
  "/wrap*" -
  "/seek*" -
  "/one*" {
   HTTP::redirect "http://www111.abc.com[HTTP::uri]"
    }
  "/secure_one*" {
   set replaceURI [string map [list /secure_one /wrap1] [HTTP::uri]]
   HTTP::redirect "$replaceURI" }
  "/seek_pond*" {
   set replaceURI [string map [list /seek_pond /wrap1] [HTTP::uri]]
   HTTP::redirect "$replaceURI" }
  "/ask_wrap*" {
   set replaceURI [string map [list /ask_wrap /wrap1] [HTTP::uri]]
   HTTP::redirect "$replaceURI" }
 }
}
