For me it is not clear why an accelerator mode WC is faster then a Transparant Mode webcache. This is how I understand both modes after googling for about half a day on this topic : WC IN TRANSPARANT MODE (WCTM), When an http request hits the WCTM for the second time, then the WC will send its cached contents back to the client. Since the info is in the cache, the real web server does not have to be contacted by the WCTM. WC IN ACCELERATOR MODE (WCAM) : when an http request hits the WCAM for the second time,the the WC will look if this request is in its cache and send the cached response of this request back to the client. Since the info is in the cache, the real web server does not have to be contaced by the WCAM. In both cases (from the second request onwards) the real web server is not contacted. So, what exactly makes an accelerator mode WC go faster then ? ____________________________________________________________________________________ Looking for last minute shopping deals?
