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"?
* 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"?

 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"?
+* 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"?
