The RewriteEngine directive is the most important directive and must be set On in order to be able to make use of URL rewriting RewriteRule is the most common directive and is used to actually change a URL Every URL that should be changed must start with the RewriteRule directive, which takes the form:

RewriteRule pattern substitution [flags]

pattern is a regular expression for Apache to match, and substitution is the string that should be substituted into a matching URL flags are optional modifiers that alter the directive mod_rewrite recognizes several wildcards when rewriting a URL, and several flags can be appended to a RewriteRule directive pattern must start with (^) and end with ($) RewriteRule also performs wildcard expansion and can backreference selected text An example of backreferencing is this:

RewriteRule ^/(important\docs) /secret/$1
QR Code ISO/IEC18004 Printer In C#
Using Barcode printer for .NET framework Control to generate, create QR Code JIS X 0510 image in VS .NET applications.
In this example, the $1 backreferences important\docs (the backslash is used to escape the period) Several backreferences can be used, by changing $1 to $N, where N represents the Nth backreference Also supported are the wildcards (), (*), and (+) The period matches only one character, the asterisk matches zero or more characters, and the plus matches one or more characters Some of the flags that can be appended to a RewriteRule directive are listed in Table VIII2

RewriteCond is also commonly used so that a condition may be tested before executing a RewriteRule directive, much like an if statement when programming The syntax for RewriteCond is:

RewriteCond testpattern condpattern [flags]
Bar Code Generation In Visual Studio .NET

where testpattern is checked against condpattern and flags are optional modifiers This can be remembered by the statement if testpattern matches condpattern, execute the following code The RewriteCond syntax includes the use of server variables, specified as %{variable}, and backreferences to text grouped by parentheses, like RewriteRule Some of the server variables supported by RewriteCond are these:
ANSI/AIM Code 128 Creation In VS .NET

A basic example of RewriteCond is this:

Using Barcode reader for VS .NET Control to read, scan read, scan image in .NET framework applications.
This would rewrite all URLs to DocumentRoot/theserverspage html only if the variable REMOTE_HOST matches theservercom Additionally, RewriteCond supports two optional flags: [OR] and [NC] [OR] is used to test multiple conditions, while [NC] is used to disable case sensitivity for both testpattern and condpattern For example:

Using Barcode printer for .NET Control to generate, create Code 3 of 9 image in .NET framework applications.
RewriteCond %{REMOTE_HOST} 192168314 [OR] RewriteCond %{REMOTE_HOST} ^thatservercom [NC] RewriteRule ^/$ /theserverpagehtml

Bar Code Creation In C#
Using Barcode generator for .NET framework Control to generate, create bar code image in VS .NET applications.
For this lab, it is assumed that the user has Apache running, with mod_rewrite installed mod_rewrite will be used to rewrite URLs for two different cases: redirecting from one server to a new server and redirecting a user to a browser-specific page, based on the Web browser being used to access the server Using the RewriteRule directive, add a line to httpdconf to redirect a user from http://oldserver/~theuser/somepath to http://newserver/ ~theuser/somepath Using the RewriteCond conditional statement, search for a user s client type and then, with RewriteRule, redirect the user to a client-specific page 1 Open httpdconf in a text editor 2 Redirect the home directories from one location to another using mod_rewrite
