[Marble-devel] technical question about http return code for empty tiles

[Anders Lund]

Hi,

It appears that map.openseamap.org returns 203 when a tile is not available. 
Is there a reason that 204 (request ok, no content) is not used?

Reason I ask is that marble keeps a cache, and I need to find out how to make 
sure that seamark tiles that were emptied (ie a light was moved out of it) are 
expired from the cache.

It appears to me that a 204 would be a reason for that, while 203 is 
questionable.
