Hi All,
I'll start off with the situation ....
I have built an RB web server which is required to serve around
100 small images via a single html page (the html page and all
images are being served via the RB web server). Although the
images are loading in the browser they seem to load one at a time
even though Safari and most browsers are able to request and
display a number ( often 4 or 8) of images at once. It seems that
my RB web server is not able to receive and respond to more than
one request at a time.
You need to handle keep-Alive sessions. If you don't handle this
correctly,
your server or the clients opens and closes a TCP connection for
each image.
While the browser might try to handle many sessions in parallel,
your RB app
is likely to establish new connections not as fast as possible.
I think Stefan has probably surmised correctly. In the HTTP 1.1
protocol keep-alive is the norm. If your server responds as a 1.1
server then the client will assume it can pipeline multiple requests
into the existing socket connection. Your server will need to handle
this pipelining properly to get the best speed. You can look at the
http rfc for more info, or just capture some packets from the same
page being requested from apache, and that should help you get an
idea of how it works.
HTH,
Kevin
