Load Balancer performance: Benchmarking HAProxy on EC2 (Quick and Dirty Style)

By on Monday, February 21st, 2011 | No Comments

Lies, Damn Lies, and Benchmarks…. I get quite frustrated with benchmarks because they are very hard to perform properly, and even when you do them properly its very hard to get any useful data from them. Its all very well knowing that a web server can do 4,000 connections per second, but what we really [...]

Apache and X-Forwarded-For Headers

By on Wednesday, February 9th, 2011 | No Comments

As a follow on to my previous blog, its easier to get Apache to log client IP addresses utilizing X-Forwarded-For headers than it is using IIS. By default, the logs do not record source IP addresses for clients but this is very easy to change using the LogFormat directive in the httpd.conf file as explained [...]

By on Friday, February 4th, 2011 | No Comments

So, you’re using IIS and you want to track your clients by IP address in your IIS logs. Unfortunately, out of the tin, this is simply not possible. The X-Forwarded-For (XFF) HTTP header is an industry standard to find the IP address of a client machine that is connecting to your web server via an [...]

GSLB – Why do Global Server Load Balancers Suck?

By on Saturday, January 15th, 2011 | No Comments

OK, Before the flames start let me state the usual caveat, “GSLBs don’t ALWAYS suck, just most of the time”. Here at Loadbalancer.org we have toyed with the idea of selling a GSLB (as most of our competitors do), it wouldn’t take long… to hack a decent PowerDNS interface onto one of our appliances… But every [...]

By on Thursday, September 16th, 2010 | No Comments

A couple of our customers have asked if our appliances would do G-Zip compression in the past we haven’t given it much thought. Then out of the blue a company offered us a card to test with http://www.aha.com/ and some of us in the office welcoming the opportunity to meddle with anything new jumped at [...]

Update: Sorry but as of Wednesday 6th Oct 2010, the free lifetime license is no longer available! OK, so let me begin by saying that I am both excited and slightly scared by our latest product.
