j o e n d S( s CGI-savvy HTTP Server.
This module builds on SimpleHTTPServer by implementing GET and POST
requests to cgi-bin scripts.
If the os.fork() function is not present (e.g. on Windows),
os.popen2() is used as a fallback, with slightly altered semantics; if
that function is not present either (e.g. on Macintosh), only Python
scripts are supported, and they are executed by the current process.
In all cases, the implementation is intentionally naive -- all
requests are executed sychronously.
SECURITY WARNING: DON'T USE THIS CODE UNLESS YOU ARE INSIDE A FIREWALL
-- it may execute arbitrary Python code or external programs.
Note that status code 200 is sent prior to execution of a CGI script, so
scripts cannot send other status codes such as 302 (redirect).

Returns True and updates the cgi_info attribute to the tuple

Returns False otherwise.
The default implementation tests whether the normalized url
path begins with one of the strings in self.cgi_directories
(and the next character is a '/' or the end of the string).

Given a URL path, remove extra '/'s and '.' path elements and collapse
any '..' references.
Implements something akin to RFC-2396 5.2 step 6 to parse relative paths.
Returns: A tuple of (head, tail) where tail is everything after the final /
and head is everything before it. Head will always start with a '/' and,
if it contains anything else, never have a trailing '/'.
Raises: IndexError if too many '..' occur within the path.
