[Tilecache] Caching external WMS through a proxy

[Jon Britton]

Thanks,

I've created a http_proxy environment variable in Windows but still no luck.
The WMS im using works without TileCache so there shouldn't be a problem
there. Here are the settings I'm using:

[oam]
type=WMSLayer
layers=world
url=http://openaerialmap.org/wms/
extension=png
bbox=-20037508.3427892,-20037508.3427892,20037508.3427892,20037508.3427892
srs=EPSG:900913

Although I'm pretty sure the problem isn't here. Is there any way I can
check whether python knows about my proxy?

Cheers,
Jon
