10,000 Virtual Hosts in a Tomcat instance

Hi, I am quite a Tomcat newbie. I am building an web application that host about 10,000 websites (only single static HTML for each website). Each website is reference using a subdomain i.e. website1.mycompany.com, website2.mycompany.com, and so on. So I am planning to add these subdomain as

Re: 10,000 Virtual Hosts in a Tomcat instance

Edoardo, The websites can be added and edited dynamically by the corresponding owners. I am buidling something like Blogger.com. Where users can edit their websites and published it. The engine is built using Tapestry. Currently, I am using a servlet filter to forward Http requests to the

Ok - Theoretically it may work... Who do you know that has a machine with Terabytes of memory? And is using it for web hosting?! The JVM will spend all its time doing context switching and garbage collection... Andrew On 26/08/2006, at 11:49 AM, Mladen Turk wrote: Andrew Miehs wrote:

Thanks Mladen for the valueable reply. Andrew, on your question : it is 10,000 domains that serves 10,000 different static HTML. One HTML for each domain. How much memory does 1 webapp takes in Tomcat ? Would it be ok with 10,000 domains pointing to 10,000 webapps but each webapp serves only

Re: 10,000 Virtual Hosts in a Tomcat instance

I tried to use only Tomcat since the static content is dynamically generated. Think blogging application. However, users dont update the data that often, that's why I generate the content and make it static for web access, as oppose to dynamically generate the content each time it is requested.

Re: 10,000 Virtual Hosts in a Tomcat instance

Dear Mladen, Are we referring to 10,000 Virtual servers or 10,000 Connections? And the answer is yes to 1 connections. Yes I would use worker-mpm or better still an epoll based httpd daemon, like lighttpd or zeus. Regards Andrew On 26/08/2006, at 12:18 PM, Mladen Turk wrote: Andrew

Re: 10,000 Virtual Hosts in a Tomcat instance

Stupid question, Why don't you implement the 'virtual' hosts inside the one 'webapp'? And not create 10,000 web apps? That the App itself deals with the virtual hosts (by reading the host header), and not tomcat? Andrew On 26/08/2006, at 12:30 PM, KEGan wrote: I tried to use only Tomcat
