Attempts to implement wildcard domain name resolution using Apache and tomcat

Http://www.java2000.net/viewthread.jsp? Tid = 5422

Do you want your server to provide an independent second-level domain name for each member? For example
Aa.test.com
Bb.test.com/blog
Of course, both AA and BB are your members.

Below are some of my successful attempts today

1. I will not talk about installing Apache, tomcat, and mod_jk. If you cannot use them, please refer to other tutorials.

2. Related configuration files

3. Description

In httpd. conf, rewrite_module and mod_jk are enabled, and tomcat connection configuration is configured.

Virtual Host Configuration is critical

Servername all-sites
Can be modified
Servername test.com
Serveralias * .test.com
In this way, you can specify the Domain Name of the VM.

Urlrewrite Configuration

1. Rewritecond % {http_host} ^ [a-z0-9/-] +/. Test/. com $
2. Rewriterule ^/(. *) $/% {http_host}/$1
3. Rewriterule ^/([a-z0-9/-] +)/. Test/. com /? $/Index. jsp? U = $1 [L, pt]
4. Rewriterule ^/([a-z0-9/-] +)/. Test/. com/blog (/(.*))? $/Blog. jsp? U = $1 & $3 [L, pt]

The first line declares that this rewrite is only interested in the Host Name (% {http_host}) similar to xxxx.test.com, which is a regular

In the second line, all requests for this domain name are rewritten for the first time, for example
Change a.test.com
/A.test.com

Set
B .test.com/blog changed
/B. Test/COM/blog

Row 3: Adjust access without Parameters
Change/a.test.com
/Index. jsp? U =

Row 4: Adjust the path with Parameters
Change/B .test.com/blog
/Blog. jsp? U = B

If there are parameters such
B .test.com/id1_3 is finally rewritten
/B .test.com/id1_3
/Blog. jsp? U = B & id = 3

I won't say much about the rest!
