Apache file locations

This module is designed for the use in test suites and large networks which have to deal with different httpd versions and different configurations. Also, these sections can be nested to achieve more complex restrictions. The most commonly used configuration section containers are the ones that change the configuration of particular places in the filesystem or webspace. First, it is important to understand the difference between the two.

The filesystem is the view of your disks as seen by your operating system. Note that forward slashes should always be used as the path separator in Apache httpd configuration files, even for Windows. In contrast, the webspace is the view of your site as delivered by the web server and seen by the client. The webspace need not map directly to the filesystem, since webpages may be generated dynamically from databases or other locations.

The same effect can be obtained using. So for example, the following configuration directives will, when placed in the main section of the configuration file, deny access to any file named private. No file called server-status needs to exist in the filesystem.

In order to have two overlapping URLs one has to consider the order in which certain sections or directives are evaluated. The same is true for the ProxyPass directives:. But see the section below on configuration merging to find out how using regex sections will change how directives are applied. A non-regex wildcard section that changes the configuration of all user directories could look as follows:. Regular expressions containing named groups and backreferences are added to the environment with the corresponding name in uppercase.

Choosing between filesystem containers and webspace containers is actually quite easy. This is because many different webspace locations URLs could map to the same filesystem location, allowing your restrictions to be circumvented. For example, consider the following configuration:. But what if you are on a case-insensitive filesystem?

An exception is filesystem links. The same directory can be placed in more than one part of the filesystem using symbolic links. Therefore, for the highest level of security, symbolic links should be disabled with the appropriate Options directive. If you are, perhaps, thinking that none of this applies to you because you use a case-sensitive filesystem, remember that there are many other ways to map multiple webspace locations to the same filesystem location.

Alternatively, to temporarily redirect all pages on one site to a particular page on another site, use the following:. This technique is called reverse proxying because the web server acts like a proxy server by fetching the documents from a remote server and returning them to the client. It is different from normal forward proxying because, to the client, it appears the documents originate at the reverse proxy server.

The ProxyPass configures the server to fetch the appropriate documents, while the ProxyPassReverse directive rewrites redirects originating at internal. It is important to note, however, that links inside the documents will not be rewritten.

So any absolute links on internal. It allows you to create maps of URLs that need to be rewritten, so that complex proxying scenarios can be handled. The directives provided by this module can use characteristics of the request such as browser type or source IP address in deciding from where to serve content.

The rewriting engine is capable of performing all three types of mappings discussed above: internal redirects aliases , external redirects, and proxying. Inevitably, URLs will be requested for which no matching file can be found in the filesystem. This can happen for several reasons. In some cases, it can be a result of moving documents from one location to another. In this case, it is best to use URL redirection to inform clients of the new location of the resource. In this way, you can assure that old bookmarks and links will continue to work, even though the resource is at a new location.

When this module is activated, it will intercept "File Not Found" errors and look for a resource with a similar filename. Managed WordPress Private Cloud 8.
