Sticky load balance with Apache HTTPD 2.2

admin — Wed, 18 Mar 2009 21:39:16 +0000

Apache HTTPD 2.2 includes some interesting features for making a basic load balancer.

This configuration makes a sticky loadbalancer with 3 backend servers. It is not dependant on any specific configuration of the backend server such as JSESSIONID or PHPSESSIONID.
It will create a BALANCEID-cookie with a route to a backend server.

#You need at least these modules #Header used for setting cookie LoadModule headers_module ... #Proxy LoadModule proxy_module ... LoadModule proxy_http_module ... LoadModule proxy_balancer_module ...


#Set a cookie if BALANCER_ROUTE_CHANGED containing BALANCER_WORKER_ROUTE environment variable

Header add Set-Cookie "BALANCEID=hej.%{BALANCER_WORKER_ROUTE}e; path=/;" env=BALANCER_ROUTE_CHANGED
#Show balancer-manager



  SetHandler balancer-manager

  Order allow,deny

  Allow from all


ProxyRequests Off
#Configure members for cluster



  BalancerMember http://b1.jakeri.net:80 route=server1

  BalancerMember http://b2.jakeri.net:80 route=server2

  BalancerMember http://b3.jakeri.net:80 route=server3


#Do not proxy balancer-manager

ProxyPass /balancer-manager !
#The actual ProxyPass

ProxyPass / balancer://jakeri/ stickysession=BALANCEID nofailover=Off

#Do not forget ProxyPassReverse for redirects ProxyPassReverse / http://b1.jakeri.net/ ProxyPassReverse / http://b2.jakeri.net/ ProxyPassReverse / http://b3.jakeri.net/

I believe that this configuration is somewhat better compared to this guide.

I got to fix my css for the :-/

Comparison between my generated images and IKEA advertisement

admin — Thu, 21 Aug 2008 21:12:07 +0000

A couple years ago I wrote a small java-program that generated a large image from a collection of thumbnails. I tested the software using thumbnails from the IKEA website.

Since the beginning of this week, IKEA is doing a advertisement on the street that resemble my old computer generated images quite well.

Could IKEA advertising agency have seen my old images…

~~Seems to be very buggy in other browsers than Safari (remember til next time, TEST). Back to the drawing table.~~

Someone found a neat way to utilise my countupdown application as a Web clip widget in OS X’s Dashboard.

Use Make Text smaller (cmd -) in Safari before using Web clip feature to make it smaller.
