i've been searching for the answers for a day or two and i still don't know how to approach this problem.
i want to make an application to upload really large files to a server. i've decided to go for the adobe air because i thought it would be less restricting than flash, anyways, i am using actionscript3.
if i wanted to use a regular file uploading class i meet a server restriction of max file size (i tried working with php).
i googled something about "chunked fileupload" where i send small amounts of 64bit encoded data to a server via urlloader class and then merge them in php. this, however, creates a massive extra upload size overhead (because of the 64bit encoded data).
another idea i read about is to use a "socket connection" send a direct tcp stream. however, i have absolutely no idea how do sockets work and what should i use as a server. i tried using some simple php socket example code found online but i didn't really understand how would i use this for fileupload and flash didn't want to connect to it anyways. maybe someone could enlighten me on that?
or maybe someone has a better experience in the chunked fileupload method? is there an already existing library for handling large fileuploads in actionscript?
really ANY advice would be appreciated, i feel kind of lost in my quest.
i do have control over the server to some extent maybe i will convince sysadmins to install some service for me.
