Apache proxying subdomain root requests

Question

Description

• Internal Tomcat server that has webapps listening on 8080:
  
  "http://internal:8080/foo-webservice/"
  "http://internal:8080/foo-website/"
  

• External facing Apache server is proxying requests for a subdomain:
  
  "http://foo.domain.com/"

• Any requests of the root of the subdomain would be proxied to the foo-website webapp on Tomcat.

• Any other requests would be proxied to the appropriate path / webapp

Use Case A

• Request:
  "http://foo.domain.com/index.html"
  

• Proxied to:
  "http://internal:8080/foo-website/index.html"
  

Use Case B

• Request:
  "http://foo.domain.com/webservice/listener.html?param1=foo&param2=bar"
  

• Proxied to:
  "http://internal:8080/foo-webservice/listener.html?param1=foo&param2=bar"
  

VirtualHost definition

• Current virtual host definition which satisfies Use Case B:

   <VirtualHost *:80> ServerName foo.domain.com ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ErrorLog /var/log/apache2/foo_error.log LogLevel warn CustomLog /var/log/apache2/foo_access.log combined # RewriteRules # ? # ProxyPass ProxyPreserveHost On ProxyPass / http://internal:8080/ ProxyPassReverse / http://internal:8080/ </VirtualHost> 

Attempt 1

    # RewriteRules
    RewriteEngine On
    RewriteRule ^/(.*) http://internal:8080/foo-website/$1 [P]

• Use Case A is satisfied
• Use Case B fails

Attempt 2

    # RewriteRules
    RewriteEngine On
    RewriteRule ^/$ http://internal:8080/foo-website/$1 [P]

• Use Case B is satisfied
• Use Case A is not completely satisfied
• The index.html in foo-website is loaded, but none of the files in the js, img or css folders.

Answer 1

ProxyPass rules match in order

 ProxyPass        /webservice/ http://internal:8080/foo-webservice/
 ProxyPassReverse /webservice/ http://internal:8080/foo-webservice/

 ProxyPass        /website/ http://internal:8080/foo-website/
 ProxyPassReverse /website/ http://internal:8080/foo-website/

 ProxyPass        / http://internal:8080/foo-website/
 ProxyPassReverse / http://internal:8080/foo-website/

No rewrite rule. Isn't that good enough ?

Answer 2

我认为您需要使用第一次尝试，但要在每个RewriteRule指令末尾的方括号中包含QSA（查询字符串追加）标志。

Answer 3

• I think the issue with Attempt 2 (none of the files in the js, img or css folders being mapped) was a sign that my approach was wrong.

• My solution now is to redirect any requests to the root, to the foo-website webapp.

    <VirtualHost *:80> ServerName foo.domain.com ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ErrorLog /var/log/apache2/foo_error.log LogLevel warn CustomLog /var/log/apache2/foo_access.log combined # RewriteRules RewriteEngine On RewriteRule ^/$ /foo-website/ [R] # ProxyPass ProxyPreserveHost On ProxyPass / http://internal:8080/ ProxyPassReverse / http://internal:8080/ </VirtualHost> 

• This was not what I originally wanted, but I think this is the resolution.
