   getting a crc from a server
  Are there any HTTP commands to get a CRC of a file from a server, or would these have to be stored as seperate files on the server?

Or you can compare the DATE header if present.  But neither of those are a CRC.There is an extension to HTTP 1.1 that gives a "Content-MD5" header.  Include "Want-Digest" in your headers.  If you see it in the response, it's supported.  Otherwise, no.frob.   ;  Hmm, that might work if my server supports it, thanks.
