NAME

       TSHttpTxnServerIntercept - intercept origin server requests

SYNOPSIS

          #include <ts/ts.h>

       void TSHttpTxnServerIntercept(TSCont contp, TSHttpTxn txnp)

DESCRIPTION

       TSHttpTxnServerIntercept()  allows  a  plugin  take  over  the servicing of the request as
       though it was the origin server. In the event a request needs to be made to the server for
       transaction  txnp,  contp  will be sent a TS_EVENT_NET_ACCEPT event. The edata passed with
       TS_EVENT_NET_ACCEPT is an TSVConn just as it would be for a normal accept. The plugin must
       act  as  if  it  is an HTTP server and read the HTTP request and body from the TSVConn and
       send an HTTP response header and body.

       TSHttpTxnServerIntercept() must be not be called after the connection to  the  server  has
       taken   place.   This   means   that  the  last  hook  that  it  can  be  called  from  is
       TS_HTTP_READ_CACHE_HDR_HOOK.  If  a  connection  to  the  server  is  not  necessary,  the
       continuation  contp  will  be sent a TS_EVENT_NET_ACCEPT_FAILED event when the transaction
       completes.

       The response from the plugin is cached subject to standard  and  configured  HTTP  caching
       rules.  Should the plugin wish the response not be cached, the plugin must use appropriate
       HTTP   response    headers    to    prevent    caching.    The    primary    purpose    of
       TSHttpTxnServerIntercept()  is  allow plugins to provide gateways to other protocols or to
       allow  one  to  plugin  to  its  own  transport  for  the  next   hop   to   the   server.
       TSHttpTxnServerIntercept() overrides parent cache configuration.

       TSHttpTxnServerIntercept()  must  only  be  called  once per transaction. The continuation
       contp must have been created with a valid TSMutex.
