yet another redirect question

so heres my question. i have a simple irule that will redirect to a new host/uri based on the incoming request. however what i'm discovering is that apparently its not as simple as i had originally thought. i dont seem to understand why the orignial URI still gets appended to the redirected uri..

 

when HTTP_REQUEST {

 

 

 

set dest https://some.host.com/singleuri

 

 

switch -glob [string tolower [HTTP::host][HTTP::uri]] {

 

"some.other.host.com/anotheruri/*" {

 

HTTP::respond 301 Location "$dest[HTTP::uri]"

 

}

 

}

 

}

 

 

this works, yet the new uri contains "/singleuri/anotheruri/".. what am I doing wrong?

    You are appending the previous URI which is contained in the [HTTP::uri] variable.

     

    If you just want it to goto https://some.host.com/singleuri change your redirect line to "HTTP::response 301 Location "$dest"

    You'd want something like this; 

    
when HTTP_REQUEST {
   switch -glob [string tolower [HTTP::host][HTTP::uri]] {
      "https://some.host.com/singleuri*" {
         HTTP::respond 301 Location "https://some.other.host.com/anotheruri/"
      }
      }
}

    Hi Dave,

    If you want to maintain any additional information in the [HTTP::uri] then you can just replace the host value and then perform a "string map" to replace the target values.

    Also, do not include the URI::protocol in the switch comparison. 

     
when HTTP_REQUEST {
switch -glob [string tolower [HTTP::host][HTTP::uri]] {
"some.host.com/singleuri*" {
HTTP::respond 301 Location "https://some.other.host.com[string map {"/singleuri" "/anotheruri"} [HTTP::uri]]"
}
}
}

    Hope this helps.
