[OpenLayers-Users] proxy not working

[george gpoul48]

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?
