Having an issue with Apache front server connecting to a Jetty application server.

I thought that ProxyPass ! in a location block was supposed to NOT pass on processing to the application server, but for some reason that is not happening in my case, Jetty shows a 404 on the missing statics (js, css, etc.)

Here's my Apache (v 2.4, BTW) virtual host block:

DocumentRoot /path/to/foo
  ServerName foo.com
  ServerAdmin webmaster@foo.com

  RewriteEngine On

  <Directory /path/to/foo>
    AllowOverride  None
    Require all granted
  </Directory>

  ProxyRequests Off
  ProxyVia Off
  ProxyPreserveHost On

  <Proxy *>
    AddDefaultCharset off
    Order deny,allow
    Allow from all
  </Proxy>

  # don't pass through requests for statics (image,js,css, etc.)
  <Location /static/>
    ProxyPass !
  </Location>

  <Location />
    ProxyPass           http://localhost:8081/
    ProxyPassReverse    http://localhost:8081/
    SetEnv              proxy-sendchunks 1
  </Location>

You need to use the ProxyPass ! argument with a path, not in a <Location> block, for example:

ProxyPass /static !
ProxyPass / http://localhost:8081/
ProxyPassReverse / http://localhost:8081/

I believe these rules are processed in the order they appear in the config, so be sure to specify exclude rules first.

The way to make it work inside Location blocks is to reverse the order, i.e. have the most specific Location statement last:

DocumentRoot /path/to/foo
  ServerName foo.com
  ServerAdmin webmaster@foo.com

  RewriteEngine On

  <Directory /path/to/foo>
    AllowOverride  None
    Require all granted
  </Directory>

  ProxyRequests Off
  ProxyVia Off
  ProxyPreserveHost On

  <Proxy *>
    AddDefaultCharset off
    Order deny,allow
    Allow from all
  </Proxy>

  <Location />
    ProxyPass           http://localhost:8081/
    ProxyPassReverse    http://localhost:8081/
    SetEnv              proxy-sendchunks 1
  </Location>

  # don't pass through requests for statics (image,js,css, etc.)
  <Location /static/>
    ProxyPass !
  </Location>

This works. See https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxypass for more details - it contains an example pretty much exactly as the above.
