1 """Wrapper for mod_fastcgi, for use as a CherryPy HTTP server when testing.
2
3 To autostart fastcgi, the "apache" executable or script must be
4 on your system path, or you must override the global APACHE_PATH.
5 On some platforms, "apache" may be called "apachectl", "apache2ctl",
6 or "httpd"--create a symlink to them if needed.
7
8 You'll also need the WSGIServer from flup.servers.

12 KNOWN BUGS
13 ==========
14
15 1. Apache processes Range headers automatically; CherryPy's truncated
16 output is then truncated again by Apache. See test_core.testRanges.
17 This was worked around in http://www.cherrypy.org/changeset/1319.
18 2. Apache does not allow custom HTTP methods like CONNECT as per the spec.
19 See test_core.testHTTPMethods.
20 3. Max request header and body settings do not work with Apache.
21 4. Apache replaces status "reason phrases" automatically. For example,
22 CherryPy may set "304 Not modified" but Apache will write out
23 "304 Not Modified" (capital "M").
24 5. Apache does not allow custom error codes as per the spec.
25 6. Apache (or perhaps modpython, or modpython_gateway) unquotes %xx in the
26 Request-URI too early.
27 7. mod_python will not read request bodies which use the "chunked"
28 transfer-coding (it passes REQUEST_CHUNKED_ERROR to ap_setup_client_block
29 instead of REQUEST_CHUNKED_DECHUNK, see Apache2's http_protocol.c and
30 mod_python's requestobject.c).
31 8. Apache will output a "Content-Length: 0" response header even if there's
32 no response entity body. This isn't really a bug; it just differs from
33 the CherryPy default.
