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_NET_EVENT_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   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.
