23 | ; assets can be requested several times in short periods | ||

26 | |||
27 | ; If a memory cache hit happens, or the asset is still in memory | ||
28 | ; due to other causes, update the timestamp on the disk file anyway. | ||

32 | |||
33 | ; Enabling this will cache negative fetches. If an asset is negative-cached | ||
34 | ; it will not be re-requested from the asset server again for a while. | ||
35 | ; Generally, this is a good thing. | ||
36 | ; | ||
37 | ; Regular expiration settings (non-sliding) mean that the asset will be | ||
38 | ; retried after the time has expired. Sliding expiration means that | ||
39 | ; the time the negative cache will keep the asset is refreshed each | ||
40 | ; time a fetch is attempted. Use sliding expiration if you have rogue | ||
41 | ; scripts hammering the asset server with requests for nonexistent | ||
42 | ; assets. | ||
43 | ; | ||
44 | ; There are two cases where negative caching may cause issues: | ||
45 | ; | ||
46 | ; 1 - If an invalid asset is repeatedly requested by a script and that asset is | ||
47 | ; subsequently created, it will not be seen until fcache clear | ||
48 | ; is used. This is a very theoretical scenario since UUID collisions | ||
49 | ; are deemed to be not occuring in practice. | ||
50 | ; This can only become an issue with sliding expiration time. | ||
51 | ; | ||
52 | ; 2 - If the asset service is clustered, an asset may not have propagated | ||
53 | ; to all cluster members when it is first attempted to fetch it. | ||
54 | ; This may theoretically occur with networked vendor systems and | ||
55 | ; would lead to an asset not found message. However, after the | ||
56 | ; expiration time has elapsed, the asset will then be fetchable. | ||

59 | ; including grids. | ||
