The cookie-flag is available in Apache 2.
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 expression. On the first RewriteRule it is applied to the URL-path of the request; subsequent patterns are applied to the output of the last matched RewriteRule.
The Pattern will initially be matched against the part of the URL after the hostname and port, and before the query string. 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 that replaces the original URL-path that was matched by Pattern. The Substitution may be a: If it does, the scheme and hostname are stripped out and the resulting path is treated as a URL-path.
Otherwise, an external redirect is performed for the given URL. To force an external redirect back to the current host, see the [R] flag below. This is used when a flag see below needs to be applied without changing the path. 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. Modifying the Query String By default, the query string is passed through unchanged.
You can, however, create URLs in the substitution string containing a query string part. Simply use a question mark inside the substitution string to indicate that the following text should be re-injected into the query string.
When you want to erase an existing query string, end the substitution string with just a question mark. To combine new and old query strings, use the [QSA] flag. Additionally you can set special actions to be performed by appending [flags] as the third argument to the RewriteRule directive.
Flags is a comma-separated list, surround by square brackets, of any of the following flags: Using the B flag, non-alphanumeric characters in backreferences will be escaped. For example, consider the rule: With the B flag, it will instead map to index. This escaping is particularly necessary in a proxy situation, when the backend may break if presented with an unescaped URL.
This has the following effect: If the rule does not match, then all following chained rules are skipped.One of the easiest ways to harden and improve the security of a web application is through the setting of certain HTTP header values.
As these headers are often added by the server hosting the application (e.g. IIS, Apache, NginX), they are normally configured at this level rather than directly in.
The first step is to add server variables named RESPONSE_SERVER and RESPONSE_X-POWERED-BY in the rewrite section of the configuration file. The configuration files will not work properly if the same .
Nov 27, · In this video we will show you how to remove "server" information from header, in Apache If you need more information you can check this post. Use the following a2enmod script to enable the headers, rewrite, proxy_http, ssl, and http2 modules: $ a2enmod headers $ a2enmod rewrite $ a2enmod proxy_http $ a2enmod ssl $ a2enmod http2 Add the following directives to the VirtualHost section of a rutadeltambor.com file.
Problem solved - for IIS 7 and above, you should see an additional column named X-Forwarded-For which contains the IP addresses of client PC’s. For IIS 6 the IP address of the load balancer should be replaced with the IP address of client PC’s. By using rule templates, rewrite maps,.NET providers, and other functionality integrated into IIS Manager, Web administrators can easily set up rules to define URL rewriting behavior based on HTTP headers, HTTP response or request headers, IIS server .
