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

[Lauri Kajan]

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?
