RAMCACHE - caching POST?

The LTM manual states: The RAM Cache feature is fully compliant with the cache specifications described in RFC 2616, Hypertext Transfer Protocol -- HTTP/1.1. This means that you can configure RAM Cache to cache the following content types:

 

* 200, 203, 206, 300, 301, and 410 responses.

 

* Responses to GET methods by default.

 

* Other HTTP methods for URIs specified in the URI Include list or specified in an iRule.

 

* Content based on the User-Agent and Accept-Encoding values. The RAM Cache holds different content for Vary headers.

 

 

And HTTP 1.1 does allow caching of the response to a POST request -- from RFC2616, section 9.5:Responses to this method are not cacheable, unless the response includes appropriate Cache-Control or Expires header fields.I'd hazard a guess that your POST response is coming back with response code 200 OK and no response headers that would prevent caching. Looking at the http profile (where RAM cache is configured), it doesn't appear that you can configure by method or response code, so the fix would be to have your servers insert cache control headers into POST responses.
