Moving a directory on your web site

For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

Apache httpd's mod_alias is part of your standard web server build ... it's the part that allows you to put alias directives into your configuration file httpd.conf to that different parts of your web tree can reside on different parts of your computer's file system. As an example, the manual that's supplied with Apache httpd will be usually be found in /usr/local/apache2/manual rather than somewhere like /home/website/htdocs/manual, and an alias command will be used to cause any requests to be served appropriately.

Mod_alias has other uses too. The Redirect directive lets you give the server that requests for a particular URL are to be passed back to the browser with a note that the file in now to be found in a new location. This uses a location header, and you can set up the redirect to be temporary or permanent.

If you have retired a whole directory of URLs and want to have any remaining request that are made for resources in it to be passed on, you can use a redirectMatch ... for example:
RedirectMatch 301 ^/modules(/.*) http://www.wellho.net/resources$1

This example is from the .htaccess file within the /modules directory on our server, and it refers all requests to the /resources directory (where they should have pointed in the first place!). So if you type http://www.wellho.net/modules/H999.html into your URL bar, you'll see that you get the page http://www.wellho.net/resources/H999.html instead, the URL bar is changed (usually - it's browser specific), and the same rule applies to any other URLs in that directory.

The complete .htaccess file, engineered to deal with mod_rewrite issues and more fully commented, is available for your use. And we would love to teach you more httpd deployment techniques on our Linux Web Server course.
