If you ever wanted to change your web site's URL scheme, this product is for you!
You can specify multiple LoadFromFile associations in configuration files. Note that large numbers of such directives may impact performance. If the sub-resource cannot be loaded from file in the directory specified, the sub-request will fail rather than fall back to HTTP fetch.
Part of the reason for this is to indicate a configuration error more clearly. As an added benefit.
If resources are loaded from file, the rewritten versions will be updated immediately when you change the associated file. Resources loaded via normal HTTP fetches are refreshed only when they expire from the cache by default every 5 minutes.
Therefore, the rewritten versions are only updated as often as the cache is refreshed. Resources loaded from file are not subject to caching behavior because they are accessed directly from the filesystem for every request for the rewritten version.
This directive can not be used in location-specific configuration sections. If you have directories or file types that cannot be loaded directly from the filesystem, LoadFromFileRule lets you add fine-grained rules to control which files will be loaded directly and which will fall back to the standard process, over HTTP.
If one does, it calculates the mapped filename and checks for applicable LoadFromFileRules. Considering rules in the reverse order of definition, it takes the first applicable one and uses that to determine whether to load from file or fall back to HTTP.
Some examples may be helpful. The first must be either Allow or Disallow while the second is a prefix that specifies which filesystem paths it should apply to.
Because the default is to allow loading from the filesystem for all paths listed in any LoadFromFile statement, most of the time you will be using Disallow to turn off filesystem loading for some subset of those paths. You would use Allow only after a Disallow that was overly general. Not all sites are well suited for prefix-based control.
Consider a site with PHP files mixed in with ordinary static files: The second argument, however, is a RE2-format regular expression instead of a file prefix. Remember to escape characters that have special meaning in regular expressions.
Consider a site with the opposite problem:As a complement to HBruijn's answer, if you opt for solution (3) "ProxyPass", you may have to also use mod_proxy_html to rewrite some URLs in your HTML pages.
cf. How to handle relative urls correctly with a reverse proxy for some examples. mod_rewrite Flags mod_rewrite uses "flags" to give our rewrite conditions and rules additional features. We add flags at the end of a condition or rule using square brackets, and separate multiple. This module implements a proxy/gateway for Apache.
It implements proxying capability for AJP13 (Apache JServe Protocol version ), FTP, CONNECT (for SSL), HTTP/, HTTP/, and HTTP/The module can be configured to connect to other proxy .

|microHOWTO: Configure Apache as a reverse proxy||DocumentRoot In deciding what file to serve for a given request, httpd's default behavior is to take the URL-Path for the request the part of the URL following the hostname and port and add it to the end of the DocumentRoot specified in your configuration files. Therefore, the files and directories underneath the DocumentRoot make up the basic document tree which will be visible from the web.|

Introduction. The Web Server is a crucial part of web-based applications. Apache Web Server is often placed at the edge of the network hence it becomes one of the most vulnerable services to attack. The Apache RewriteRule documentation says that to perform an external redirect back to the current host, you have to use the [R] flag rather than just using an absolute URL in the substitution.
I. This meant that Apache now passes through all the information Django needs to properly build absolute URLs, we just need to make Django parse them properly.
Solving the problem – Django By default, Django ignores all X-Forwarded headers.
