"""Wrapper for mod_wsgi, for use as a CherryPy HTTP server.
|
|
|
|
To autostart modwsgi, the "apache" executable or script must be
|
|
on your system path, or you must override the global APACHE_PATH.
|
|
On some platforms, "apache" may be called "apachectl" or "apache2ctl"--
|
|
create a symlink to them if needed.
|
|
|
|
|
|
KNOWN BUGS
|
|
==========
|
|
|
|
##1. Apache processes Range headers automatically; CherryPy's truncated
|
|
## output is then truncated again by Apache. See test_core.testRanges.
|
|
## This was worked around in http://www.cherrypy.org/changeset/1319.
|
|
2. Apache does not allow custom HTTP methods like CONNECT as per the spec.
|
|
See test_core.testHTTPMethods.
|
|
3. Max request header and body settings do not work with Apache.
|
|
##4. Apache replaces status "reason phrases" automatically. For example,
|
|
## CherryPy may set "304 Not modified" but Apache will write out
|
|
## "304 Not Modified" (capital "M").
|
|
##5. Apache does not allow custom error codes as per the spec.
|
|
##6. Apache (or perhaps modpython, or modpython_gateway) unquotes %xx in the
|
|
## Request-URI too early.
|
|
7. mod_wsgi will not read request bodies which use the "chunked"
|
|
transfer-coding (it passes REQUEST_CHUNKED_ERROR to ap_setup_client_block
|
|
instead of REQUEST_CHUNKED_DECHUNK, see Apache2's http_protocol.c and
|
|
mod_python's requestobject.c).
|
|
8. When responding with 204 No Content, mod_wsgi adds a Content-Length
|
|
header for you.
|
|
9. When an error is raised, mod_wsgi has no facility for printing a
|
|
traceback as the response content (it's sent to the Apache log instead).
|
|
10. Startup and shutdown of Apache when running mod_wsgi seems slow.
