Clientside files download problem

Clientside files download problem

first. I’m not good for english sorry for if understand too hard.

Garrysmod Dedicated Server on windows vista 32bit:

I’m using http file server(aka HFS, like ftp, makes my server to web server http://www.rejetto.com/wiki/index.php/HF...roduction)

and using sv_downloadurl “http://ipjuso.ath.cx” (it will be on when i turn on HFS)

and my clients download under the cache/dua files everytime when they are connect.

everything ok but problem is why they downloads cache files everytime. but dont download if client have addons.(ex: if client have hoverboard. dont download related cache files.)

and this problem is not for maps. clients dont download maps if they are downloaded once or have it.

How do i fix this problem? it waste everyone’s time and my system resouces.

Thanks for read.
