Can I use aliases with wildcards in mod_cluster and JBoss?

[jbossolo]

Hi all!

I hope to write in the right place, I'm missing the classic forum style...

I'm working with Apache 2.2, mod_cluster 1.2 and JBoss EAP 6.1, someone told me to deploy an application that should serve a lot of different URLs, like:

• blablaone.acme.com
• blablatwo.acme.com
• blablathree.acme.com
• ...
• blablatoomany.acme.com

all of these names are DNS aliases of the IP that Apache is listening on.

I'm lazy, so in JBoss I tried to define an alias with a wildcard:

<virtual-server name="default-host">

     <alias name="blabla*.acme.com"/>

</virtual-server>

But I've got no luck, Apache is answering with an error 404.

If I specify every alias like this, it works:

<virtual-server name="default-host">

     <alias name="blablaone.acme.com"/>

     <alias name="blablatwo.acme.com"/>

     <alias name="blablathree.acme.com"/>

</virtual-server>

Could someone tell me if there is a way to avoid to manage that list of a lot of aliases and just use an *?

Thanks for your attention.

An Alias can't have a wild-card. You have http://docs.jboss.org/mod_cluster/1.2.0/html/native.config.html#d0e505 to switch off the Alias logic in mod_cluster.

Ok thanks!

So, no UseAlias.

The solution to my problem is to use a wild-card in the ServerAlias and to create a specific balancer, like this:

CreateBalancers 1

<VirtualHost xxx.xxx.xxx.xxx:80>

     ServerAlias blabla*.acme.com

     <Proxy balancer://myacmebalancer>

          ProxySet stickysession=JSESSIONID|jsessionid

          ProxySet nofailover=On

     </Proxy>

</VirtualHost>

And so on, different virtualhosts with different balancers for the other applications.

Bye!
