EntityTagVersion

data class EntityTagVersion(val etag: String, val weak: Boolean) : Version

This version checks the etag value and pass it through conditions supplied by the remote client. Depending on the conditions, it produces the return value of enum type VersionCheckResult.

It never handles If-None-Match: * as it is related to non-etag logic (for example, Last modified checks).

Return

VersionCheckResult.OK if all headers pass or there was no related headers, VersionCheckResult.NOT_MODIFIED for successful If-None-Match, VersionCheckResult.PRECONDITION_FAILED for failed If-Match

Parameters

etag
  • entity tag, for example file's content hash

weak
  • whether strong or weak validation should be applied
