Add INKHttpIsInternalRequest to sdk documentation
--------------------------------------------------
Key: TS-251
URL: https://issues.apache.org/jira/browse/TS-251
Project: Traffic Server
Issue Type: New Feature
Reporter: Miles Libbey
Assignee: Diane Smith
Where it should live : HTTP Functions
What it does : Check if the state machine/request is internal
Prototype : bool INKHttpIsInternalRequest(INKHttpTxn txnp);
Description :
Provides an API to distinguish between internal and external requests.
Internal requests are those Checks if request being handled originated from
with the traffic server process.
Returns : true if the request originated from within the traffic server process
background info
Some plugins (like those modifying cache-control behaviors) need to know
whether the current state machine that they are running within was originated
by an external connection (through the http port) or as an internal one such as
one created by something like InkHTTPConnect.
Currently, there is no way for
- the state machine to know whether its a state machine created by an
external connection or one that is internal
- since the State Machine itself doesn't know how it was created, plugins
have no way of knowing either
