Re: mod_proxy and mod_perl in guide
These are protected files so we have to use authentication and authorization that is done by mod_perl. And Internet Explorer that use most of our customers has bug that prevents displaying of PDF (and any other large non-dynamic non-HTML) files if the URL to that file was result of Redirect. Thanks for help.

mod_proxy and mod_perl in guide
Hi! I have one question. According to the Guide there's buffering feature of mod_proxy that allows to release heavy mod_perl process from delivering data over slow connection to the user. In our system we have to pass large PDF files thru mod_perl to proxy and we noticed that it takes the same time as sending it directly to customer. After checking Apache code for mod_proxy looks like it is normal behaviour. File modules/proxy/proxy_util.c function ap_proxy_send_fb. This function reads from originating server into buffer and then writes to the customer from this buffer. BUT the socket is closed AFTER all the data is sent to the client (file module/proxy/proxy_http.c function ap_proxy_http_handler. So the heavy mod_perl server is not released for serving other requests untill the data is sent to the client by proxy. Maybe I'm missing something but the practice shows that this is true and Guide contains error. Please someone check this. Thank you Andrei

Those of us who have tried the two-server setup have all seen dramatic reductions in the number of mod_perl processes required. - Perrin

Thanks Vivek, Andrei, use the front end to directly handle any binaries, static files, etc. I doubt they are generating of these on the fly.
