[OpenLayers-Users] WFS ProxyHost

Tue Feb 17 12:25:55 EST 2009

Hi,

for local addresses you don't need a proxy host. To be sure, that your local
address is used I would use relative path.

OpenLayers.ProxyHost="/cgi-bin/proxy.cgi/?url="

and you can also try to load your WFS with relative path. Then the proxy
script is not used. Not 100% sure but only addresses, which begins with http
, use the proxy script.

// Layer WFS
                wfs = new OpenLayers.Layer.WFS(
                "Quadras WFS",
                "/geoserver/wfs",
                {typename: 'topp:quadra'},

If your WFS is now loaded, then there seems something wrong with your proxy
script or configuration. If not loaded, copy the WFS request from firebug
into the address bar of your browser, to be sure that the request send a
valid response.

Betreff: [OpenLayers-Users] WFS ProxyHost

Hi!

I'm having some troubles on trying to use WFS...

As suggested in the FAQ, and put the proxy.cgi on cgi-bin Apache folder, and
add the line "AddHandler python-cgi-script .cgi" on httpd.conf, as suggested
in http://gist.fas.harvard.edu/chgis/?p=14.

But loading the following page, I receive the error 1012, on Firebug.

Help please!!!
