Leif Hedstrom commented on TS-1622:
-----------------------------------
I'd like to propose this API addition:
{code}
/**
Test whether a request / response header pair would be cacheable under the
current
configuration. This would typically be used in
TS_HTTP_READ_RESPONSE_HDR_HOOK, when
you have both the client request and server response ready.
@param txnp the transaction pointer
@param request the client request header. If NULL, use the transactions
client request.
@param response the server response header. If NULL, use the transactions
origin response.
@return 1 if the request / response is cacheable, 0 otherwise
*/
tsapi int TSHttpTxnIsCacheable(TSHttpTxn txnp, TSMBuffer request, TSMBuffer
response);
{code}
> Add an API to query if a response header would be cacheable

> It would be useful for a plugin to be able to take e.g. a response header (a
> Hdr object) and ask the HttpSM if this response would be cacheable or not. It
> should use the same logic (and configs) as the core does normally.
