Mobile redirect iRule :uri "/groupon" to m.site.com/19550

Hello Network Engineers asked to be overnight developers :),

 

I am asked to write a redirect iRule.

 

Here is what I came up with -->

 

when HTTP_REQUEST { if { [string tolower [HTTP::uri]] starts_with "/groupon" } { HTTP::redirect "m.site.com/1231" } if { [string tolower [HTTP::uri]] starts_with "/shoprunner" } { HTTP::redirect "m.site.com/1232" } if { [string tolower [HTTP::uri]] starts_with "/hilton" } { HTTP::redirect "m.site.com/1233" } }

 

This is a small set. The full iRule would be hundreds of redirects in one irule for one VIP.

 

  1. Will the code work
  2. Should it be done (i know it shouldn't but so far have not given an argument that swayed the business).

Any help would be greatly appreciated.

 

Thanks in advance,

 

-Greg

    Slight modification to my posted code. subsequent if statements are elseif

     

    when HTTP_REQUEST { if { [string tolower [HTTP::uri]] starts_with "/groupon" } { HTTP::redirect "m.site.com/1231" } elseif { [string tolower [HTTP::uri]] starts_with "/shoprunner" } { HTTP::redirect "m.site.com/1232" } esleif { [string tolower [HTTP::uri]] starts_with "/hilton" } { HTTP::redirect "m.site.com/1233" } }

      Thanks for the comment nitass. That is a great article. I don't think it will work in this situation. That article replaces one uri with another. The requirement is to redirect to a different site bases upon the uri and rewrite the url and uri. original site is "site.com" the new site is "m.site.com". I should have made that clear in the original post.

    I don't think it will work in this situation.

    why not?

    e.g.

     config

[root@ve11a:Active:In Sync] config  tmsh list ltm virtual bar
ltm virtual bar {
    destination 172.28.24.10:80
    ip-protocol tcp
    mask 255.255.255.255
    profiles {
        http { }
        tcp { }
    }
    rules {
        qux
    }
    source 0.0.0.0/0
    vs-index 9
}
[root@ve11a:Active:In Sync] config  tmsh list ltm rule qux
ltm rule qux {
    when HTTP_REQUEST {
  if { [class match -- [string tolower [HTTP::path]] starts_with redirect_class] } {
    HTTP::redirect "http://[class match -value [string tolower [HTTP::path]] starts_with redirect_class]"
  }
}
}
[root@ve11a:Active:In Sync] config  tmsh list ltm data-group internal redirect_class
ltm data-group internal redirect_class {
    records {
        /groupon {
            data m.site.com/1231
        }
        /hilton {
            data m.site.com/1233
        }
        /shoprunner {
            data m.site.com/1232
        }
    }
    type string
}
