Using OpenLayers API with proxy - OSM tiles blocked

Hi !
we’re developing a system with Openlayers maps API in our company
our proxy blocks all tiles view from OpenStreetMaps and leave us with blank map (panel is showed)
my questions is :

  1. is there any way to recive a list of servers to add into our whitelist in order to view tiles ?
  2. in this case … is it possible to work with domain names insted of IP list ?

thanks in advance.

Are you able to display other OSm based tiles like the listing


Yes, im able to display it.
this is part of our code : (maybe using OpenLayers.Projection(“EPSG:4326”) is wrong?)

map = new OpenLayers.Map(“mapdiv”);
map.addLayer(new OpenLayers.Layer.OSM());

epsg4326 =  new OpenLayers.Projection("EPSG:4326"); //WGS 1984 projection
projectTo = map.getProjectionObject(); //The map projection (Spherical Mercator)

Maybe you can find some hints about projection on ?

But what is your problem now? Proxy server or projection?

I assume that a wrong projection has no influence on a proxy server, not?

Are you able to display the main website example
on by choosing standard layer (that is default there) when you are behind your proxy?

main panel appears to be OK
but tiles are not displayed
looks like its having trouble to connect to a.tile.openstreetmap

The standard mapnik layers is served from, and, as can be deduced by looking at the page info on a web browser with full access, or looking at the configuration information in JOSM. This is on both port 80 as HTTP: and port 443 as HTTPS:.

However, these tiles are only provided to assist people contributing to the map and for proof of concept application use. You should be planning to use your own tile server in the medium to long term, so, given your draconian firewalling, I would suggest you go down that path immediately.
