While we won't cover implementation and configuration of a virtual domain here, as far as the web server is concerned, we will, instead, focus on how to transfer the files from your previous to your new server. text/html 2009-09-12T12:46:12+02:00 http://www.systemengineers.de/apache/tutorials/mod_rewrite_part1?rev=1252752372 by Dirk Brockhausen ---------- You may have encountered the name „mod_rewrite“ before when surfing the web. For all of our readers who are not intimately familiar with this nifty Apache Web Server module - and, of course, for those who don't know it all - we are presenting this small introductory tutorial as a multipart serial. text/html 2009-09-12T12:46:12+02:00 http://www.systemengineers.de/apache/tutorials/mod_rewrite_part2?rev=1252752372 by Dirk Brockhausen ---------- In this tutorial's last instalment we started off with a discussion of the basics of Module mod_rewrite. In the example reviewed there we made use of a rule which, put in full words, states: „If access to file .htaccess is attempted, return an error message stating that access is denied.“ text/html 2009-09-12T12:46:12+02:00 http://www.systemengineers.de/apache/tutorials/mod_rewrite_part3?rev=1252752372 by Dirk Brockhausen ---------- In the two preceding parts of this tutorial we explained the basics of Rules and Conditions. We will now follow up with two examples to illustrate their use for somewhat more complex applications. The first example deals with dynamicall generated pages while the second example will cover calling up “.txt“ files. text/html 2009-09-12T12:46:12+02:00 http://www.systemengineers.de/apache/tutorials/mod_rewrite_part4?rev=1252752372 by Dirk Brockhausen ---------- In this final part of our tutorial we will take a look at those special directives we haven't covered yet. These directives cannot be defined on directory level. This means that you will have to be able to edit the Apache webserver's configuration file (httpd.conf). These permissions will usually only be assigned to users „root“ or „admin“. text/html 2009-09-12T12:46:12+02:00 http://www.systemengineers.de/apache/tutorials/mod_rewrite_part5?rev=1252752372 Creating the Rules The Building Blocks of Mod-Rewrite URL Redirection Rules: Special Characters Along with regular expressions, mod-rewrite allows for the use of special characters. It's a good thing to understand what these are before you begin writing rules. (Mainly because you need one or more of them in almost every rule.) text/html 2009-09-12T12:46:12+02:00 http://www.systemengineers.de/apache/tutorials/mod_rewrite_using_regular_expressions?rev=1252752372 Understanding How to Create Regular Expressions to Use in Mod-Rewrite URL Redirection When using Mod-Rewrite for URL Redirection, it is very important to be able to use regular expressions. Why? Because, if you can't you will have to have a separate rule (or condition) for every page you want to rewrite. (On one Macwom's, Inc. site, this is over 500 pages... Not very practical.) text/html 2009-09-12T12:46:12+02:00 http://www.systemengineers.de/apache/tutorials/modrewrite-force-www?rev=1252752372 Um den Aufruf der Domain systemengineers.de als www.systemengineers.de zu erzwingen fügt Ihr folgendes in die Config ein. RewriteEngine On RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule .* http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L] text/html 2009-09-12T12:46:12+02:00 http://www.systemengineers.de/apache/tutorials/save_traffic_with_mod_deflate?rev=1252752372 General In this tutorial I will describe how to install and configure mod_deflate on an Apache web server. mod_deflate allows Apache2 to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_deflate, you can compress HTML, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier. text/html 2009-09-12T12:46:12+02:00 http://www.systemengineers.de/apache/tutorials/serve-alternate-content-based-on-time?rev=1252752372 Time-dependant rewriting Time-dependant rewriting uses mod_rewrite and apache server time variables to display different files depending on the time, while the URL stays the same. An often requested implementation of this is to display a different home page or image depending on if its morning, noon, or night.
