Apache alias and re write as a logarithmic equation

This gives you the ability to negate a pattern; to say, for instance: This can be used for special cases where it is better to match the negative pattern or as a last default rule. When using the NOT character to negate a pattern you cannot have grouped wildcard parts in the pattern.

This gives you the ability to negate a pattern; to say, for instance: This can be used for exceptional cases, where it is easier to match the negative pattern, or as a last default rule. When using the NOT character to negate a pattern you cannot have grouped wildcard parts in the pattern.

This is impossible because when the pattern does NOT match, there are no contents for the groups. Substitution of a rewriting rule is the string which is substituted for or replaces the original URL for which Pattern matched.

The server-variables are the same as for the TestString of a RewriteCond directive. The mapping-functions come from the RewriteMap directive and are explained there.

Why Do Servers Use Redirects?

These three types of variables are expanded in the order of the above list. As already mentioned above, all the rewriting rules are applied to the Substitution in the order of definition in the config file. The URL is completely replaced by the Substitution and the rewriting process goes on until there are no more rules unless explicitly terminated by a L flag - see below.

There is a special substitution string named '-' which means: No, it is useful to provide rewriting rules which only match some URLs but do no substitution, e.

You can even create URLs in the substitution string containing a query string part. When you want to erase an existing query string, end the substitution string with just the question mark. There is a special feature: When you prefix a substitution field with http: This auto-reduction on implicit external redirect URLs is a useful and important feature when used in combination with a mapping-function which generates the hostname part.

Have a look at the first example in the example section below to understand this.

An unconditional external redirect to your own server will not work with the prefix http: To achieve such a self-redirect, you have to use the R-flag see below. Additionally you can set special flags for Substitution by appending [flags] as the third argument to the RewriteRule directive.

Flags is a comma-separated list of the following flags: If you want to use other response codes in the range just specify them as a number or use one of the following symbolic names: Use it for rules which should canonicalize the URL and give it back to the client, e. When you use this flag, make sure that the substitution field is a valid URL!

If not, you are redirecting to an invalid location! And remember that this flag itself only prefixes the URL with http: Usually you also want to stop and do the redirection immediately.

To stop the rewriting you also have to provide the 'L' flag. Use this flag to mark pages which no longer exist as gone. You have to make sure that the substitution string is a valid URI e.Feb 17,  · I understand the Apache developers resistance to including this functionality as document_root should not be relied upon to give the correct path if mod_alias/mod_rewrite etc have done some funky magic.

Apache’s mod_alias provides the Redirect and RedirectMatch directives, which provide a means to redirect one URL to another.

This kind of simple redirection of one URL, or a class of URLs, to somewhere else, should be accomplished using these directives rather than a mod_rewrite RewriteRule.

Die PC-FAQ enthält Antworten zu vielen Fragen rund um den PC, sowie Erklärungen der häufigsten Computerbegriffe und ein Wörterbuch. The [L] means last. What you really need to use as well is the [PT] flag to indicate that the resultant path from your rewrite rule should be passed through to next handler which in your case is the alias directive.

There are two methods for setting up Drupal with Apache on Ubuntu. The first (preferred) method edits the virtual host configuration, which is the default setup on Ubuntu (even for a single-site web server).

Using a high trace log level for mod_rewrite will slow down your Apache HTTP Server dramatically! Use a log level higher than trace2 only for debugging!
