[Opensim-dev] GetAssetStreamHandler, grid mode and caching

[Diva Canto]

Tommil,

RegionAssetService is meant to be an http service to get assets from 
regions when they run in standalone mode. Hence that  original logic it 
had for being enabled on the Hypergrid. In gridmode+HG, that module is 
not enabled.

If you want to get assets from regions when you are in gridmode, you 
should use the AssetCache, obviously. I suggest you don't touch 
GetAssetStreamHandler, because (I think) that's meant to be what it is: 
the raw request. It's your code's business to figure out what to do in 
these different modes.

We can go into the old discussion about the complexity of managing 
standalone vs grid mode, and all the headaches, but that's a much deeper 
issue...
