| 20 | == Overview == |
| 21 | |
| 22 | Currently the tile service has no support for http cache semantics. |
| 23 | |
| 24 | == Motivation == |
| 25 | |
| 26 | HTTP caching is a very simple way of increasing performance. |
| 27 | |
| 28 | Proxy servers cannot currently cache MapGuide GETTILEIMAGE responses, |
| 29 | without custom configuration and overrides |
| 30 | |
| 31 | == Proposed Solution == |
| 32 | |
| 33 | Adding cache headers to tile service. |
| 34 | |
| 35 | This would require support adding the source tile timestamp |
| 36 | to the HTTP header and then support returning 304's as required |
