<p>One of the biggest complaints about AJAX, that I hear, is that it’s
difficult to escape your own domain (actually host, protocol and port)
It’s easy enough to use an <a href="http://www.w3.org/2006/webapi/"
title="W3C do web services" target="_blank">XHR object</a> to retrieve
an XML document (or whatever) from within your own domain but a soon as
you try to get an <a href="http://blogs.law.harvard.edu/tech/rss"
title="RSS definitive guide" target="_blank">RSS</a> feed or access a <a
href="http://en.wikipedia.org/wiki/Representational_State_Transfer"
title="Wikipedia REST page" target="_blank">REST</a> service on
another box your stuffed.</p>
<p>Well you might not be quite as stuffed as you thought. I hope this
helps those of you who think .htaccess is only good for redirects and
adding passwords.</p>
<p>If you use Apache as your web server, and I’m sure you are (although
other web servers may be just as good or better) you’ll hopefully know
about <a href="http://httpd.apache.org/docs/1.3/howto/htaccess.html"
title="Apache tutorial page" target="_blank">.htaccess</a> files. If
you don’t they are plain text files that tell apache to do stuff before
returning the page.</p>
<p>There is a little feature of Apache called mod_rewrite. It’s a
rule-based rewriting engine to rewrite requested URLs on the fly. It
can be used to make your URLs pretty but here it’s going to act as our
proxy.</p>
<p>First create a file called .htaccess with the following code.</p>
<p class="code">RewriteEngine on<br>
RewriteRule ^/call/(.*)$ <a class="moz-txt-link-freetext" href="http://backstage.bbc.co.uk/$1">http://backstage.bbc.co.uk/$1</a> [P]</p>
<p>Then all you need to do is on your server create a folder called
“bbc” or whatever. Upload this file to it and that folder will act as a
proxy server to your AJAX application. Nice, Job done and only two
lines of code.</p>
