Re: [OpenLayers-Users] proxy not working

Hi George,

maybe you indeed need a proxy. You are running your servers in a same host, but in different ports, right? I'm not an expert on this, but I think that's the case. From the proxy point of view, they're not a same host.
I am still thinking that this could be an IIS related problem. I tried your proxy and it seemed to be working when accessing openlayers.org or openstreetmap.org. But when I tried to access your server (Jetty?), I get these:

http://84.205.237.73/script/proxy.py?url="">

Some unexpected error occurred. Error text was: <urlopen error [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond>

P.S. I think you could also set some proxy up in your IIS so that e.g. all the requests made to host/geoserver/ would redirect to host:443/ or something like that..

It is working without proxy only in localhost, but not from the internet. That is why i used proxy. Is it possible to run without proxy? Regarding iis i have no idea what it should be. IIS configured and tested to run python without problem. Any idea?

thank you all for your concern

Hi Ivan and George,

I just tested the site and it seems that the request sent works. Also the proxy works. But do you need proxy when using GetFeatureInfo?

maybe this has something to do with IIS?

Hi,


first check if the normal request is working, without proxy. What does
firebug say if its not working?
