[OpenLayers-Users] OpenLayers.Request.POST/GET errors

[Brent Pedersen]

hi, i havent followd this thread, but have you looked at this?
http://trac.openlayers.org/wiki/FrequentlyAskedQuestions#ProxyHost

you can't make an AJAX request to a remote server, it looks like
that's what you're doing.
if that's the case, use a proxy. if it's not, then use a relative url.
