Apache config for all Location except specific URI

I need to apply some configuration for a Location Directive.

These configurations must be applied for all location, except some URIs (e.g. I don't wanna change configs for /products, so bellow configuration must be applied for all locations, except /products )

<Location />
 # desired configurations
</Location>
Solution

  • This can be done in several ways:

    1. Using regex

    Use regex in Location Directive to match all URIs, except your pattern

    e.g.:

    <Location ~ "^((?!/product).)*$">
# desired configurations
</Location>

    2. Using < If> directive

    e.g.: use If inside your directory:

    <If "%{Request_URI} != '.*/product.*'">

    or

    <If "%{Request_URI} != '^((?!/product).)*$'">

    3. By setting variables and using If and IfDefine

    Set a variable at start of configurations, and then use directive

    SetEnvIf Request_URI ".*/product.*" isProd=1
...
<IfDefine isProd>
...

    or you can use expr in If directive for comparing strings and variables.

    4. By using another <Location>

    It's possible to change an earlier <Location> section by overriding it after. For example, this will enforce authentication on everything but /.well-known/, a common pattern to get TLS certificates from Let's Encrypt:

            <Location />
                AuthType Basic
                AuthName "Restricted Content"
                AuthUserFile /etc/apache2/htpasswd
                Require valid-user
        </Location>
        <Location /.well-known/>
                Require all granted
        </Location>

    This will ask users for passwords in all of /* except for /.well-known/* which will not require a password.

    See the upstream documentation on configuration sections for more information on this.
