[OpenLayers-Dev] Caching layerimages by browsers

[Andy Deakin]

Hi,

I have not looked at the firefox bug in detail, but would it be possible 
to simply add a query string at the end of the requested tile (with that 
string being unique to that tile) if the chosen browser is FF, e.g.
rather than url.com/zzz/xxx/yyy.png use 
url.com/zzz/xxx/yyy.png?hash=OL.hash(xxxyyyzzz)

Does the firefox hash take into account the query string? Would this 
cause problems with any tile servers?
