proxy: explicit & transparent + VideoCache

["pavel kolodin" <pavelkolodin@xxxxxxxxx>]

My squid + videocache returns HTTP 303 (see other) with URL  
"http://10.10.10.1/videocache/youtube/1231...5151.flv"; to browser.

If i set proxy address and port in browser's settings, browser will do  
request to "http://10.10.10.1/videocache..."; returned with 303 by squid  
and successfully downloads wideo.

But if browser don't know about proxy and im using transparent proxy  
(iptables -> REDIRECT -> 80 to 3128) then browser won't request  
"http://10.10.10.1"; (to be more precise - flash plugin won't do that  
request), but all pages and picrutes and SWFs etc. downloads OK.

Why?
