POIs there more than GET or POST for HTTP?

copied!<p>I'm learning about writing Apache modules for a project I'm working on. I found the <a href="http://httpd.apache.org/docs/2.4/developer/" rel="nofollow">official guide</a>, which turns out to be <em>very</em> informative.</p> <p>On the first page, "<a href="http://httpd.apache.org/docs/2.4/developer/modguide.html" rel="nofollow">Developing modules for the Apache HTTP Server 2.4</a>", the section "Building a handler", subsection "The <code>request_rec</code> structure" provides some example code:</p> <pre><code>static int example_handler(request_rec *r) { /* Set the appropriate content type */ ap_set_content_type(r, "text/html"); /* Print out the IP address of the client connecting to us: */ ap_rprintf(r, "<h2>Hello, %s!</h2>", r->useragent_ip); /* If we were reached through a GET or a POST request, be happy, else sad. */ if ( !strcmp(r->method, "POST") || !strcmp(r->method, "GET") ) { ap_rputs("You used a GET or a POST method, that makes us happy!<br/>", r); } else { ap_rputs("You did not use POST or GET, that makes us sad :(<br/>", r); } /* Lastly, if there was a query string, let's print that too! */ if (r->args) { ap_rprintf(r, "Your query string was: %s", r->args); } return OK; } </code></pre> <p>Something that caught my eye was the <code>strcmp</code> on <code>r->method</code> to see if it's <code>POST</code>, <code>GET</code>, or <em>something else</em>. That's weird. I thought the only HTTP methods were <code>GET</code> and <code>POST</code>? Is there something else, or just the developers (or documentors) being unneedingly cautious?</p>
