Diva, Tommil,<BR>
<BR>
as being the one actually introducing the Get/SetAssetStreamHandlers, I can tell you that they are quite simply just that - handlers for incoming requests for assets.<BR>
<BR>
Whether they should be cached or not is of course subject to the same questions as any 'should this be cached' discussion.<BR>
<BR>
I see no reason why they shouldn't be. The reason they aren't is because they are jurassic - stemming from the 'true alpha' days when caching would just add another layer to debug.<BR><BR>Best regards,<BR>Stefan Andersson<BR><BR><BR><BR> <BR>> Date: Sun, 26 Apr 2009 09:40:44 -0700<BR>> From: diva@metaverseink.com<BR>> To: opensim-dev@lists.berlios.de<BR>> Subject: Re: [Opensim-dev] GetAssetStreamHandler, grid mode and caching<BR>> <BR>> Tommil,<BR>> <BR>> RegionAssetService is meant to be an http service to get assets from <BR>> regions when they run in standalone mode.

It's your code's business to figure out what to do in <BR>> these different modes.<BR>> <BR>> We can go into the old discussion about the complexity of managing <BR>> standalone vs grid mode, and all the headaches, but that's a much deeper <BR>> issue...<BR>> <BR>> Crista<BR>> <BR>> Tommi Laukkanen wrote:<BR>> > Hello<BR>> > <BR>> > Does someone know why GetAssetStreamHandler is not using cache but<BR>> > fetching data directly from database with asset data plugin?
