Request logging

Logs the request.

subrequests to return a document other than that requested or

to check what the response would be if a request was made

for a different resource.

Modules register handlers for the phases during which they

need to influence the handling of the request. Generally a

module will only register handlers for one or two phases.

Directives implemented by a module are described in the

chapter that covers the main phase handled by that module.

Post-Read Request Phase

This is the first phase in the request handling process. At this

point, only the values of the request line and of the HTTP

request headers are available. The proxy module uses this

phase to prepend the string

proxy: to the URI for requests it

handles, so that other modules do not inadvertently handle

those requests.

This phase is also used to set environment variables based on
