Apache ProxyPass: standalone vs location tag?

Question

How do these two code blocks differ?

ProxyPass /app http://10.0.0.10/blah
ProxyPassReverse /app http://10.0.0.10/blah

versus

<Location /app>
    ProxyPass http://10.0.0.10/blah
    ProxyPassReverse http://10.0.0.10/blah
</Location>

Thanks!

Using the Location Directive is the preferred method to use. The alternative syntax of Proxypass like this ProxyPass /app http://10.0.0.10/blah can have performance impact when there are many. However depending on your need the alternative syntax might be better.

From the documentation:

The following alternative syntax is possible, however it can carry a performance penalty when present in very large numbers. The advantage of the below syntax is that it allows for dynamic control via the Balancer Manager interface:

ProxyPass "/mirror/foo/" "http://backend.example.com/"

Please have a look at the documentation for more info.
