Difference between revisions of "Talk:WMS Tiling Client Recommendation"

Revision as of 22:36, 31 October 2006

Things that need to be constrained to ensure URLs are identical between clients and therefore cachable:

Encoding of URL elements, like ":" and " ". Are they encoded? In the case of " " is it with "+" or "%22"? Basically the URL encoding needs to be "strict" and no "loosy goosy" (except remember that WMS is messed up and specifies that you do *not* encode the "," between layer names in the "layers" parameter, even though the URL encoding rules say you should. But for "," characters *within* the layer names, those you should encode. (Like it would have killed them just to say "no commas in the layer names" and follow the URL encoding rules correctly... but I digress.)
Precise minimum of WMS parameters, and their precise ordering. All mandatory WMS parameters need to be included, fer sher.
The case of WMS parameters. Is it "VERSION" or "version"? "GetMap" or "getmap"?
