Package cgi implements CGI (Common Gateway Interface) as specified
in RFC 3875.
</p>
<p>
Note that using CGI means starting a new process to handle each
request, which is typically less efficient than using a
long-running server. This package is intended primarily for
compatibility with existing systems.

<p>
In the call graph viewer below, each node
is a function belonging to this package
and its children are the functions it
calls&mdash;perhaps dynamically.
</p>
<p>
The root nodes are the entry points of the
package: functions that may be called from
outside the package.
There may be non-exported or anonymous
functions among them if they are called
dynamically from another package.
</p>
<p>
Click a node to visit that function's source code.
From there you can visit its callers by
clicking its declaring <code>func</code>
token.
</p>
<p>
Functions may be omitted if they were
determined to be unreachable in the
particular programs or tests that were
analyzed.

<h2 id="Request">func <a href="http://localhost:6060/src/net/http/cgi/child.go?s=604:641#L19">Request</a></h2>
<pre>func Request() (*<a href="../index.html">http</a>.<a href="../index.html#Request">Request</a>, <a href="../../../builtin/index.html#error">error</a>)</pre>
<p>
Request returns the HTTP request as represented in the current
environment. This assumes the current program is being run
by a web server in a CGI environment.
The returned Request&#39;s Body is populated, if applicable.
</p>
<h2 id="RequestFromMap">func <a href="http://localhost:6060/src/net/http/cgi/child.go?s=1163:1231#L42">RequestFromMap</a></h2>

<p>
RequestFromMap creates an http.Request from CGI variables.
The returned Request&#39;s Body field is not populated.
</p>
<h2 id="Serve">func <a href="http://localhost:6060/src/net/http/cgi/child.go?s=3875:3913#L136">Serve</a></h2>
<pre>func Serve(handler <a href="../index.html">http</a>.<a href="../index.html#Handler">Handler</a>) <a href="../../../builtin/index.html#error">error</a></pre>
<p>
Serve executes the provided Handler on the currently active CGI
request, if any. If there&#39;s no current CGI environment
an error is returned. The provided handler may be nil to use
http.DefaultServeMux.
</p>
