[OSGeo-UK] How do you use OpenLayers.ProxyHost?

[Peter Cotroneo]

Hi,

 

I'm running into a cross-site scripting issue with OpenLayers.loadURL,
and I'm not sure how to use OpenLayers.ProxyHost.  I can't seem to find
any documentation that says where to specify this parameter (in
JavaScript code, a config file, etc.).

 

My JavaScript code looks like this:

 

var uri = "http://46.137.1.44/gazetteer/postcode?q=" + queryText;     

       

OpenLayers.ProxyHost="proxy.php?q="+queryText;

 

OpenLayers.loadURL(uri, '', this, pcInfo, pcFailure);

 

And my PHP proxy looks like this:

 

<?php

$ IP_ADDRESS = '46.137.1.44';

  echo file_get_contents('http://' . $IP_ADDRESS .
'/gazetteer/postcode?q=' . urlencode($_GET['q']));

?>

 

The proxy is running on a LAMP stack.  I've used this proxy for a
straight AJAX call, and it works fine.  I'm assuming, then, that I'm
using OpenLayers.ProxyHost incorrectly.

 

Any ideas?

 

Cheers,

 

Peter
