Help for Cache Storage Reuse
Use this form to define settings related to the storage reclamation process (also known as garbage collection).
Cache Storage Reuse
Proxy servers use the storage reclamation process (garbage collection) to delete files that should no longer be cached. Files are deleted based on their expiration status and size. You can turn the storage reclamation process on or off, define how much memory the process can use, and set a time of day for the process to run.
- Check the Enable storage reclamation (garbage collection) box. Generally, if you have enabled caching, you will also enable the storage reclamation process. If you do not, the size of the cache file could grow beyond the maximum size you set for it.
- Fill in values for the following fields:
- Maximum memory available for garbage collection - specify how much memory (in kilobytes) the storage reclamation process can use. The process works best if it can read all cache information into memory at one time. The amount of memory needed will vary based on dynamic changes such as the directory structure of cached files. If garbage collection fails because there is not enough memory on your system, set this field to a smaller value. If you have plenty of memory to spare, you may want to set this value above the default of 500.
- Time of day for garbage collection - specify a time (in 24:00 hour format) to run the storage reclamation process. By specifying a daily time for garbage collection, you can remove cached files before the cache reaches its maximum size. (The process runs automatically when the cache size limit is reached.) Generally, you would want the garbage collection process to run when your server is not being used heavily. This is why the default is 03:00.
