How to manage attachments on a 2nd server ?

[reverse1312]

Hello

We have a community on the video subject which could have the use of big files uploaded (for example high definition video samples)

For attachments, we use a special directory instead of the database integration option.

To preserve the bandwidth of the vbulletin/joomla server, I wish to redirect the this directory on another server with another domain name.

How could it be possible ? Is there a code hack to make ?

Thanks
