[MapProxy] EPSG:4326 requests from a Tile Source

[Jason Lee]

Hi Oliver,
I have been trying the mentioned setup in the past few days but with no luck
(accessing EPSG:900913 tiles in EPSG:4326 projection). When I try a sample
WMS fetch ("cache2" in your example), the server seems to be taking forever
to process but never responds.

Here is my sample request (somewhere in UK) :-
http://localhost:8080/service?VERSION=1.1.1&REQUEST=GetMap&SRS=EPSG:4326&BBOX=-6.14923138083586,50.5891706243825,.65875337292708,53.279367067595&WIDTH=1068&HEIGHT=422&LAYERS=cache2&STYLES=&EXCEPTIONS=application/vnd.ogc.se_xml&FORMAT=image/png&BGCOLOR=0xFFFFFF&TRANSPARENT=TRUE<http://atlas:8080/service?VERSION=1.1.1&REQUEST=GetMap&SRS=EPSG:4326&BBOX=-6.14923138083586,50.5891706243825,.65875337292708,53.279367067595&WIDTH=1068&HEIGHT=422&LAYERS=proj_tiles&STYLES=&EXCEPTIONS=application/vnd.ogc.se_xml&FORMAT=image/png&BGCOLOR=0xFFFFFF&TRANSPARENT=TRUE>

Regards,
Jason
