Christopher, Thanks for your response. I'm trying to understand also how MapServers' WFS works. As far as I know, from my experience, which is not much, whenever I wanted to make a getFeature request from a JavaScript client using a filter I used AJAX Post requests and passing the data of the Filter as an XML string in the method 'xhr.send(params)'.
>Generally, the "TEMPLATE" error message means that you are not providing >enough information for MapServer to determine that the request >is intended to be a WMS or WFS request. In this case, it looks like you are >not including any of the parameters like SERVICE:WFS, >version strings, etc. in your request URL; It is possible that MapServer can >therefore not determine that this is a WFS request Finally I get some light of what the hell could be an error like "TEMPLATE ....", I didn't found anything about it related to WFS getFeature Requests. >I don't know WFS well, but my recommendation would be to add additional WFS >parameters -- possibly an action, possibly a service, >possibly others -- and see if that improves the situation any. The problem here is that if set to the onlie resource the parameter SERVICE=WFS, then MapServer asks for another parameter, VERSION, and then for another one, REQUEST, and then for another one, TYPENAME, but this is not what I want because I make filters on the fly and I pass them as POST parameter, and also this filters maybe complex and very long, so I think is not possible in my case to do it like that. The most strange thing is that I can get the data not using the proxy-script, but whenever I pass through the proxy-script, there are problems. I think that there might be the problem... Thanks anyway, I'll continue seeking.
