I am using a PHP5 Script which the $USER download and execute on her/his
machine... It works under Linux/BSD/Windows using "php-cli". But my
tool is very specifc to my PostgreSQL.
My question is: Where is the problem coding a script which:
1) get the md5sum of the original file
2) split the original file into chunks of e.g. 1 MByte
3) get the md5sums of all chunks
4) send the index file with all chunks and md5sums to the server
5) send request for chunkupload and $SERVER answer with
a) "yes, send it"
b) "no, I have it already send next one"
6) If all chunks are complete, Script on Server put all chunks
together and check md5sum
7) $SERVER send ACK or NACK back.
If you use a session_cache or something like this, such uploads can be
done over several days with several interuptions...
It is realy easy to code...
Need only the SERVER side script (maybe with Webserver; I have a bad
experience with TCP connections from php5) and the CLIENT side script.
