Redirecting 404 to a friendly page by uri

I'm sorry one more question. What if it was a vanity domain (controlled by host header) on the same VIP that I refer to above. would it work too? something like

when HTTP_REQUEST {
 
      set host [string tolower [HTTP::host]]

      }
when HTTP_RESPONSE {
    switch [HTTP::status] {
  
   "404" {
   switch -glob $host {
    
   "*.vanitydomain.com/*" { 
     
   HTTP::respond 301 \
     
   "Location" "http://www.vanitydomain.com/moved.html" \
     
   "Server" "www.vanitydomain.com"
    
} 
   } 
  } 
 } 
}

I'm not sure if I'm even close on this nor how to stick it in the other irule.

I again really appreciate the help, I'm learning a lot.

So to keep it dynamic, you could grab the host header on HTTP_RESPONSE, and use that variable later on down the line.

when HTTP_REQUEST {
 set host [string tolower [HTTP::host]]
 set path [string tolower [HTTP::path]]
}

when HTTP_RESPONSE {
switch [HTTP::status] {
  "404" {
   switch -glob $path {
    "/agency1*" { 
     HTTP::respond 301 \
     "Location" "http://$host/agency1/moved.html" \
     "Server" "$host"
    }
    "/agency2*" { 
     HTTP::respond 301 \
     "Location" "http://$host/agency2/moved.html" \
     "Server" "$host"
    }
   } 
  } 
 } 
}
 

Thanks for helping me under stand this. You are helping me with 2 issues now. I tried a variety of ways to make /agency2 a vanity domain but not having much luck Could I just get one more sample leaving /agency1 the way it is, agency2 is now www.agency2.com?

 

 

my other issue? yeah is it an iRule with 88 "if" statements in it. I'm hoping I can apply what I'm learning here to that.

 

 

Thanks again!

The above iRule is completely agnostic in regards to hostname, the redirect is to the same hostname that was originally in the host header.

 

 

If you're adding to an existing iRule you might want to create a test VIP and use curl or wget to make sure you're getting the expected responses.

 

oh I completely missed how you added the "$host" to the second part. That make sense except that I wouldn't be matching /agency2 anymore. It would need to be a condition of 404 + host so I thought I would have to do another "switch"

 

 

I could just keep the vanity domains separate or just deal with them when someone requests it

 

 

I do have a test vip that mirrors production, I'm not going to add this to my huge redirect irule, just going to keep it separate. It seems to be happy that way. I'll save my "whats the best way to handle a rule with 88 if statements in it" for another discussion as I have taken too much of your time already :) Thanks a bunch
