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).

GET and HEAD also support running CGI scripts.
The POST command is *only* implemented for CGI scripts.

Returns True and updates the cgi_info attribute to the tuple
(dir, rest) if self.path requires running a CGI script.
Returns False otherwise.
If any exception is raised, the caller should assume that
self.path was rejected as invalid and act accordingly.
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 and returns a colllapsed path.
Implements something akin to RFC-2396 5.2 step 6 to parse relative paths.
The utility of this function is limited to is_cgi method and helps
preventing some security attacks.
Returns: The reconstituted URL, which will always start with a '/'.
Raises: IndexError if too many '..' occur within the path.
