Logfiles and gzip_loader.php

Is it normal that all files served with gzip_loader.php show a "GET //....." instead of "GET /...." in the logfiles? Why is it "//"? Does this have a special meaning? BTW these files are already cached and have a 304 status code.

Looks like there is a problem with the engine for cached files. If i deactivate js and css caching in dolphin the double slashes disappear. With caching the GET looks like this

"GET //plugins/jquery/themes/images/ui-bg_glass_75_e6e6e6_1x400.png HTTP/1.1" 200 458 "http://www.mysite.com/gzip_loader.php?file=bx_templ_css_27522f7b44788758324234234.css ..................."

I really want to fix this. Everything from the internet i read about removing leading // via mod_rewrite didn't work for me. As soon as i use dolphins caching system they are back. Why get rid of it if everything works fine you might ask? If i can trust some websites, this can affect page ranking by google. I want to get sure this will not happen. So where it comes from?
