[OpenLayers-Users] GetFeature with WFS protocol doesn't return features

[Gery .]

Could you paste the server responses and URL? I've never work with proxi.cgi because I test and run things in local machines for both client and backend. I've read once some problems about longer strings, perhaps that's the issue.

I think I found the reason, but not yet any solution.

Actually the response that wfs-server sent was not valid. It was cutted after around 23000 characters.
What could affect that. Is it the proxy.cgi that cannot pass longer strings or is something else?
