Re-use same connection for multiple tiles #24

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
It could be faster to use one connection for multiple tiles. 

First we should determine whether the current implementation reuses the
connection behind the scenes in .Net

CloudMade has explicit support for requesting multiple tiles at once,
documented at:
http://developers.cloudmade.com/issues/show/120

URL pattern:
http://<server>/tile/streamer?t=<comma separated tile numbers
X,Y,X,Y,X,Y,X....>&z=<zoom_level>&size=<64,256>&style=<style_id>&api_key=<api_ke
y>

Response format:
<X_tile 1><Y_tile 1><tile_size 1><tile 1>
<X_tile 2><Y_tile 2><tile_size 2><tile 2>
... 
<X_tile n> <Y_tile n><tile_size n><tile n> 

<X_tile> - X coordinate of tile, 4 bytes integer 

<Y_tile> - Y coordinate of tile, 4 bytes integer 

<tile_size> - byte count of tile, 4 bytes integer 

<tile> - raw bytes of PNG
