[OpenLayers-Users] free proxy wfs

[Phil Scadden]

While proxies seem to cause a lot of grief, it is really is best just to 
get on with it and use one. I have used Protocol.script when running 
without a server (off a USB), but there are enormous mountains to climb 
in making this work well. The example proxies available are simple 
whitelist proxies but a proxy can be so much more - modifying responses 
on the fly with complex joins, managing security filters, enabling 
user-specified servers etc.

Also, think a bit before setting a WFS vector layer. This means drawing 
and symbolizing is done by javascript interpretor on your browser which 
is very much slower than WMS server. Consider using WMS for display, WFS 
for query.
