Cause

This problem occurs if the following conditions are true:
  • The client tries to access the ISA Server to cache responses to client requests.
  • The size of the file that the client requests is larger than 64 kilobytes (KB).
  • The client tries to access the same file and the ISA Server sends an "If-Modified-Since" request to the Web server.
  • The Web server responds with an HTTP status code "304 Not Modified" message to the file request.
  • The ISA Server sends the requested file from the cache, and then tries to delete the cached file.
Under these conditions, the Web proxy service may stop responding.
