<h2>Overview</h2>
<p>WSAPI includes a set of helper libraries to make writing applications and web frameworks easier.
To use these libraries just <code>require</code> them in your application or framework.</p>
<h2>Request</h2>
<p><strong>wsapi.request.new(*wsapi_env*)</strong> - creates a new request object wrapping *wsapi_env*</p>
<p><strong>req.GET</strong> - table with GET parameters of request</p>
<p><strong>req.POST</strong> - table with POST parameters of request</p>
<p><strong>req.method</strong> - request method (usually "GET" or "POST") </p>
<p><strong>req.path_info</strong> - PATH_INFO metavariable</p>
<p><strong>req.script_name</strong> - SCRIPT_NAME metavariable</p>
<p><strong>req.query_string</strong> - unparsed query string</p>
<p><strong>req.params</strong> - union of <strong>req.GET</strong> and <strong>req.POST</strong>, built on demand</p>
<p><strong>req.cookies[<em>name</em>]</strong> - gets value of a cookie from browser</p>
<h2>Response</h2>
<p><strong>wsapi.response.new([<em>status</em>, <em>headers</em>, <em>body</em>])</strong> - creates a new response
object, optionally setting an initial status code, header table and body contents</p>
<p><strong>res.status</strong> - status code to be returned to server</p>
<p><strong>res.headers</strong> - table with headers to be returned to server</p>
<p><strong>res[<em>name</em>]</strong> - same as <strong>res.headers[<em>name</em>]</strong>, unless <em>name</em> is a field in res</p>
<p><strong>res[<em>name</em>] = <em>value</em></strong> - same as <strong>res.headers[<em>name</em>] = <em>value</em></strong>, unless <em>name</em> is
a field in res</p>
<p><strong>res:write(<em>s</em>)</strong> - adds <em>s</em> to the body if it is a string, if it is a table
concatenate the contents of the table and add to the body</p>
<p><strong>res:set_cookie(<em>name</em>, <em>value</em>)</strong> - sets the value of a cookie</p>
<p><strong>res:delete_cookie(<em>name</em>)</strong> - erases a cookie from browser</p>
<p><strong>res:finish()</strong> - finishes response, returning status, headers and an iterator for the body</p>
<h2>Util</h2>
<p><strong>wsapi.util.url_encode(<em>s</em>)</strong> - encodes <em>s</em> according to RFC2396</p>
<p><strong>wsapi.util.url_decode(<em>s</em>)</strong> - decodes <em>s</em> according to RFC2396</p>
