    Hi there,

    I need a solution to supply big files over a webserver. Those should be downloaded auth-protected (login/passwd) over http and php.

    Until now I used mod_xsendfile (click) with Apache 2.2 to do this. This works like a charm tested with maxsize of 100MB. It's a small extension for apache that get's active by a header-manipulation (via php) after the file was requested by the user...

    Now it's necessary to cover files up to 5 GB.

    Has somebody experience with those large files? I don't have anyone so it's hard for me to estimate this.

    Perhaps it's better to bet on Lighty webserver instead using apache?

    thx for help.

    I don't think it's a problem to serve large files with a normal Apache or Lighttpd installation (without any extra modules). When you download a Linux DVD or CD iso file, the isos are also being served by a normal Apache or Lighttpd.

    hi falko,

    thx for reply.
    top forum. top support. and top ISPCONFIG. I love it!

    My doubts to provide a large file came up that the file gets served dynamic by php.

    Some time ago I tried to this to supply a 100MB file.

    When I clicked on download the download started extremely delayed. I think this happened because php was loading the whole file in memory before it began to start it.

    I tested a workaround I read on php.net to supply the file as chunked file segmemts but it didn't solved the delay at all.

    So at all I switched over to use mod_xsendfile for apache. And this works very great.

    And that's why I'm so afraid. If mod_xsendfile won't work with files upto 5 gb I'll have no chance to get it work with apache :)

    thx and best regards,
    marco

    If you want to use PHP for processing the download, you can find some classes here: http://www.phpclasses.org/browse/

    We're using one of these classes to process our VM downloads, but I don't remember the name or link of the class...
