Apache and mod rewrite and htaccess redirect

Here are some examples:

The cookie-flag is available in Apache 2. The RewriteRule directive is the real rewriting workhorse.

The directive can occur more than once, with each instance defining a single rewrite rule. The order in which these rules are defined is important - this is the order in which they will be applied at run-time.

Pattern is a perl compatible regular expressionwhich is applied to the current URL.

Apache module mod_rewrite

This may not be the originally requested URL, which may already have matched a previous rule, and have been altered. Some hints on the syntax of regular expressions: Any single character [chars] Character class: For more information about regular expressions, have a look at the perl regular expression manpage " perldoc perlre ".

If you are interested in more detailed information about regular expressions and their variants POSIX regex etc. This enables you 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.

Note When using the NOT character to negate a pattern, you cannot include grouped wildcard parts in that pattern. This is because, when the pattern does NOT match ie, the negation matchesthere are no contents for the groups.

The substitution of a rewrite rule is the string which is substituted for or replaces the original URL 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.

These three types of variables are expanded in the order above. As already mentioned, all rewrite rules are applied to the Substitution in the order in which they are defined in the config file.

The URL is completely replaced by the Substitution and the rewriting process continues until all rules have been applied, or it is explicitly terminated by a L flag. There is a special substitution string named '-' which means: This is useful in providing rewriting rules which only match URLs but do not substitute anything for them.

It is commonly used in conjunction with the C chain flag, in order to apply more than one pattern before substitution occurs. 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 any of the following flags: This has the following effect: If the rule does not match, then all following chained rules are skipped.

The domain field is the domain of the cookie, such as '. You can use this flag more than once, to set more than one variable. Use this to strip information from URLs, while maintaining a record of that information.

Reasons for URL tidying

Use this flag to mark pages which no longer exist as gone. This corresponds to the Perl last command or the break command in C. Use this flag to prevent the currently rewritten URL from being rewritten further by following rules.

This corresponds to the Perl next command or the continue command in C. Use this flag to restart the rewriting process - to immediately go to the top of the loop. Be careful not to create an infinite loop! On sub-requests it is not always useful, and can even cause errors, if the complete set of rules are applied.

Use this flag to exclude some rules. To decide whether or not to use this rule: In these cases, use this flag. You must make sure that the substitution string is a valid URI typically starting with http: If not, you will get an error from the proxy module.

Use this flag to achieve a more powerful implementation of the ProxyPass directive, to map remote content into the namespace of the local server.

This flag is just a hack to enable post-processing of the output of RewriteRule directives, using Alias, ScriptAlias, Redirect, and other directives from various URI-to-filename translators.

You must use this flag if you want to mix directives from different modules which allow URL-to-filename translators.Provides howto-like srmvision.comss rewrite rules with explantion to migrate a domain to a new domain.
