Reverse Proxy replacement

Hey guys.

 

 

I am trying to help a customer replace the Netscape reverse proxy with BigIP. They are looking at a lot of other services on BigIP too, this just adds to the value proposition. Anyway, on with the show...

 

 

 

Customer requests a site:

 

www.company.com

 

 

request is sent to the RP. The RP does a redirect to:

 

http://www.company

 

RP does an internal DNS lookup on:

 

http://www.company

 

This is internal name resolve only and serves the connection.

 

 

 

I can see a couple of ways to do this with standard re-write options in the BigIP or by iRule, but what is throwing me is getting the name resolution portion. I saw a iRule that does this without DNS. I am looking for this with DNS.

 

 

There are about 15 different URL's for me to do so a modular approach to this would be great if the rule would look long and drawn out.

 

 

Thanks in advance,

 

T

    Well, the NAME::lookup command will allow you to do a DNS lookup via an iRule. You could then process the response and proceed accordingly.

     

     

    There's an example of it and the associated configuration changes needed here: Click here

     

     

    HTH,
