Redirecting 404 to a friendly page by uri

I try to stay away from if statements, no good excuse other than switches are sometimes faster.

Try this, it should do the trick for you.

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

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

I must be missing something in general because that doesn't work for me either. I obviously changed the 3 sanitized variables in your example.

 

 

Any other ideas? I do know that if statements are bad, but is there any technical reason mine didn't work?

Sure, it would seem that your $path isn't hitting.

Try the same with some logging as the default action, then check /var/log/ltm for further information.

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

when HTTP_RESPONSE {
switch [HTTP::status] {
  "404" {
   switch -glob $path {
    "/agency1" { 
     HTTP::respond 301 \
     "Location" "http://www.main.com/agency1/moved.html" \
     "Server" "www.main.com"
    }
    default {
     log "We have a miss, the actual path is $path"
    } 
   } 
  } 
 } 
}
 

You probably want to add a * to the end of /agency1 to match paths starting with /agency1. Without the asterisk, it will only match on the exact /agency1 path.

Not if she's redirecting it to "http://www.main.com/agency1/moved.html" :-)

 

 

edit: I suppose if it's only triggering on 404's it should be okay with an asterisk.

 

Ok the wildcard on Wil's code seems to do what I wanted it to.

 

 

if I'm directing to a real .html as in http://www.main.com/agency1/moved.html it won't meet the condition 404 AND /agency1* right? I can say I don't understand Wil's code enough to know for sure but you all brought it up :)

 

 

Thanks!

 

 

 

EDIT: opps posted this before I saw your edit :)

 

Sorry to bug you but I'm thinking ahead and if agency2 finds out we are doing this for agency1, they are going to want it too. What is the most efficient way to do this for agency2 as well? or is just adding another irule with /agency2's info good enough?

You can easily add another clause to the switch.

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

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

I'm always so nervous posting my newbie questions here and I'm always smiling at the at results, Thanks for all the help. One last question and I'll try to answer it myself. I think you did pretty much answer it in the log example I just want to make sure its the right way to do this. Also if the statement is in the right place.

Scenario 3: Big boss says "we are doing this for the agencies, why can't we return a generic moved.html for anything that doesn't match /agency1 and /agency2?"

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


when HTTP_RESPONSE {

switch [HTTP::status] {
   "404" {
   
    switch -glob $path {
    
        "/agency1*" { 
     
         HTTP::respond 301 \
     
        "Location" "http://www.main.com/agency1/moved.html" \
     
        "Server" "www.main.com"
    
         }
    
        "/agency2*" { 
     HTTP::respond 301 \
     
        "Location" "http://www.main.com/agency2/moved.html" \
     
        "Server" "www.main.com"
    
         }
 
         default {
      HTTP::respond 301 \
     
         "Location" "http://www.main.com/moved.html" \
     
          "Server" "www.main.com" 
          } 
   
     } 
  
  } 
 
} 

}

It that right?

(sorry the format is a little silly, it never lets me copy/paste from notepad++)

Careful here. Technically, yes... just keep in mind that this will be the default action when somebody is presented with a 404.
