HcMaxDiskSpaceUsage

  • 發行項

The HcMaxDiskSpaceUsage property specifies whether IIS limits the number of bytes of disk space occupied by compressed files in the compression directory.

Disk space limiting is performed, and HcMaxDiskSpaceUsage is checked by IIS, only if HcDoDiskSpaceLimiting is set to true. If HcMaxDiskSpaceUsage is set to 4294967295, there will be no limit on the number of bytes occupied by compressed files.

The metabase represents unlimited as the DWORD value of 4294967295 (0xFFFFFFFF); however, VBScript represents unlimited in hexadecimal format as &HFFFFFFFF. Previous versions of IIS represented unlimited as -1.
