Help cleaning up IRule redirect with URI rewrite.

Hi Cameron,

 

 

I understand redirecting old.host.name/abc to new.hostname.name/def. But why are you trying to redirect new.host.name/def back to /abc?

Well, not really, and that's the part that I need some help with. The second lookup is used to cut out the part of the original URI that I want to remove.

 

So, from the original uri /abc?xxxxxxx I want to remove just /abc and replace it with new.hostname.name/def. The problem that I'm running into is getting a way to match just the /abc from the original call.

 

I've put some comments in below to show what I'm trying to do so that you guys can tell the right way to do it.

 

 

Thanks all,

IRule:

 

when HTTP_REQUEST {

 

set urlredir [class match -value [HTTP::uri] starts_with DATA-GROUP]

 

[HTTP::uri] = old.host.name/abc?xxxxxxxxx

 

urlredir = new.host.name/def

 

if { $urlredir ne "" }{

 

set replace [class match -value $urlredir starts_with DATA-GROUP]

 

replace = old.host.name/abc without any of the passed arguments.

 

set redir [string map "$replace $urlredir" [HTTP::uri] ]

 

redir = the original uri where /abc is replaced with new.host.name/def

 

and become new.host.name/def?xxxxxxx

 

HTTP::redirect ""

 

then redirected.

 

}

 

}

 

 

Data external group:

 

"/abc" : = "new.host.name/def",

 

"new.host.name/def" : = "/abc",

 

 

 

It looks to me like you are trying to capture the HTTP::query and then verify the HTTP::path ends with your Data Group Value.

 

 

Example: www.website.com/abc?value=100

 

 

HTTP::uri = /abc?value=100 (Includes "/")

 

HTTP::path = /abc (Includes "/")

 

HTTP::query = value=100 (Does not include "?")

 

 

You should try setting a variable to capture the query and then compare the path. Then redirect to the next destination and append the HTTP::query.

Michael, that is exactly what I needed. Thanks very much.

Hi cdougall, so what did you end up writing for your irule? I am trying to do this same thing. oldhost.domain.com/abc/ redirect to newhost.domain.com/def/
