IIS Reverse Proxy?

We are going to be implementing an external blog, outblog.othercompany.com, that we're going to be referencing using www.ourcompany.com/blog. It has been suggested to us that we use IIS reverse proxy by implementing the Application Request Routing extension so that users hit our domain and all requests are sent over to the blogging company keeping our url intact.

 

 

I've reviewed the document and it seems straight forward, but I'm wondering if it's possible to do the same thing using iRules.

 

 

Has anybody ever tried to do this?
