Apache mod_redirect is Human Being's Saver
I have a few static web pages submitted to some scientific search engines such as citeseer. So I would like to keep them forever. How to integrate them to my dynamic weblog however presented a challenge. Luckly I found mod_redirect to be the saver.
I can simply delete my old static pages, and use mod_redirect to redirect the old URLs to the new URLs generated by my dynamic weblog. For example, to redirect my old "publications.htm" to my weblog's "publications" category, I just need add the below line to httpd.conf:
Redirect permanent /publications.htm http://www.jihe.net/research/publications/
With above, when visiting the non-existing publications.htm, instead of getting a 404 "not found" error, the web browser and search enginee will be taken to the new location http://www.jihe.net/research/publications/ and the new content will be indexed.
