Getting around CORS with IRULES

Our website uses AJAX requests that makes requests from a page delivered from VIP A (www.acmecorp.com) to send requests to VIP B (api.acmecorp.com). We had to go ahead and put in a bunch of headers ...

    you can use the ProxyPassV10 irule for this.

     

    your datagroup content would look like this: www.acmecorp.com/api/ api.acmecorp.com/ pool_api_servers

     

    the virtual server's default pool should be the one for the www.acmecorp.com servers and you must use a oneconnect profile in the VS as well.

     

    the proxypass irule will rewrite any request going to www.acmecorp.com/api/XYZ to api.acmecorp.com/XYZ and send it to the pool pool_api_servers proxypass will also take care of the location header in http redirects and rewrite it for you.

Another question, we have three LTMs sometimes we need to route to a different VIP that only exists on one of the three LTMS. If I get a request on LTM1 and need to get it to a VIP that only exists on LTM2 is that possible?

 

Absolutely, assuming the LTMs can route to/from one another. If so, you could create a pool on LTM1 that contains the VIP on LTM2, or you could simply use a node command in an iRule. Depending on how the traffic needed to flow, you could just send the request to this pool or node, or you could issue a sideband call within a request or response, ask the LTM2 VIP something, get a response, and then carry on with the original request and traffic flow.
