Hi there!

This is a message I sent to Falko, and he kindly suggested that I posted it here. Hope someone can help me with this. Here it goes...

Hi Falko

I'm sorry I'm contacting you about mod_cband, but I subscribed to
mod_cband forums last week, but it seems the site is not very active...
I read your mod_cband tutorial and put it to work. It works, but I'm
just having one problem and I was wondering if you might help me find a
solution.

I load the module and configure a virtual host to use mod_cband. I do
not put any limit on the number of allowed connections, but I will never
be able to establish more than 2 connections to the site at the same
time. Let me illustrate it with an example. These are the mod_cband
directives for the virtual host site:

RewriteEngine On
RewriteOptions inherit
CBandSpeed 2048 0 0
CBandScoreboard /srv/scoreboard/www.mydomain.com.scoreboard
CBandLimit 200MB
CBandPeriod 1D

on httpd.conf this is what I have:

CBandScoreFlushPeriod 100
CBandRandomPulse On

and on mod_cband.conf I just have the SetHandler stuff to acess the
status page.

now I access my www.domain.com and I the site won't accept more than 2
connections at the same time, i.e. photo galleries run slower, I
download 2 files at the same time and unable to browse/download anything
else until 1 of the files has been donwloaded.

I change CBandSpeed to 2048 60 60 and it's just the same. And the most
curious thing is that for the other virtual hosts sites I do not have
any mod_cband directive and I also get this 2 connection limit. The only
thing I can do is to unload the module, and everything runs fine again.

I run SuSe 10.1 and compiled the module myself. Can you help me?

TIA,

Ignacio

This has nothing to do with mod_cband, but with your browser. I get the same if I, for example, download MySQL dumps with phpMyAdmin on a server that doesn't use mod_cband. If I download two dumps at the same time, I cannot browse the same web site at the time. The only solution is to use another browser (e.g. if you download with Firefox, use IE for browsing during that time).
