One Vs for Redirects

This will work fine. For manageability, I'd use a data group with your host names defined. Then you can simply matchclass against it (barely tested code below!):

 

 
 when HTTP_REQUEST { 
  
 if { [matchclass [HTTP::host] equals dc-post] } { 
 log local0. "Got a match!" 
 HTTP::redirect http://[string map -nocase {"www" "my"} [HTTP::host]][HTTP::uri] 
 } else { 
 HTTP::respond 200 content " Sorry, no match " 
 } 
  
 } 
 

 

 

Where the data group has 'www.foo.com', 'www.bar.com' or whatever domains you want.

 

 

HTH,

How do I define the data group, also this seems to be set up just to redirect to the same domain... Can you spell out how one accomplish 3 (or more reidrects) in one iRule?

 

 

For example, redirect www.my.domain.com to www.domain.com , redirect .anotherdomain.com to www.foofoo.com, redirect .joeshouse.com to www.myhouse.com

 

 

when I tried to do it without a data group the second elseif seems to be ignored...

 

 

Thanks much apprecaite!

For this I'd use 'findclass'. First, define a data group with your redirects via the gui (iRules->Data Group List->create, give it a name and then use type 'string'). Define a space-separated list of the domains like:

www.my.foo.com www.foo.com

Where the following rule should redirect you to the www.foo.com domain if they come in with www.my.foo.com:

 
 when HTTP_REQUEST {  
     set Host [findclass [HTTP::host] your_datagroup_name " "] 
     if { $Host ne "" } { 
          HTTP::redirect $Host[HTTP::uri] 
          } 
  } 
 

I've not tested the iRule above but it should get you very close. I'd add an else statement to handle hosts that don't match.

HTH,

Great thanks, that will work for redirecting to the same domain.. But what if I want to do multiple redirects and send them to multiple different domains??

 

 

redirect www.me.com to www.you.com.. etc etc..

 

 

Doing it the dirty way... My original issue is It seems to ignore the elseif statement after the first if...

 

 

What I need to accomplish is have 1 VS to handle multiple Redirects to different domains... not necessarily always the same domain..

 

 

thanks again!

The second domain in the data group is the destination; it doesn't have to be the same domain at all (using the most recent version of the rule posted). The first domain in the data group is the match, the second is the destination for the redirect. For example:

 

 

www.original.domain.com www.yahoo.com

 

www.orig2.domain.com somewhere-else.com

 

 

Stack up as many as you need in the data group!

Gotcha, good idea on the find clasee statment. But it doesn't seem to work for me, did it work for you?

The following rule works for me - note: I'm using version 10.1 for this testing. What version are you using? I ask because the way we reference data groups has changed and that may be affecting you.

Step 1: I created a data group called 'dc-post' and added two entries - note that I left the 'value' field blank.

"www.foo.com www.google.com"

"www.bar.com www.yahoo.com"

  
   when HTTP_REQUEST {    
       set Host [findclass [HTTP::host] dc-post " "]  
  log local0. "Host var is $Host"   
       if { $Host ne "" } {   
            HTTP::redirect http://$Host[HTTP::uri]   
            }   
    }  
  

Note that there's one change to the rule above: I added the 'http://' to the redirect. It'll work either way, but my original rule was confusing (for it to work you'd need to specify 'http://www.foo.com' in your data group for the first field as opposed to just the hostname). Sorry for the confusion on that.

At any rate, this appears to be working fine. Please let me know if you still have problems.

Ahh I'm on 9.4.8, and yes that makes more sense now with the 'http://'

 

 

I couldn't find how you define the data group in 9.4.8 vs 10.1

 

 

If you can help me out there I'd appreciate it.. and also point me to the reference material on data groups that would be helpful as well..

 

 

Thanks, much appreciated!

Here is a article explaining a bit about classes on v10
