I have a large set of web files on a server, with the file structure http://datavis.ca/ books/ courses/ gallery/ papers/ ... On my development/test server, these are stored under ~friendly/datavis.ca/ books/ courses/ gallery/ papers/ ... and I view them as http://my.test.server/datavis/ but that path is *not* the DocumentRoot on that server. Thus, in an HTML file within the datavis.ca tree, if I write <a href="/papers/asa92.html"> ... that will work OK on the web server, but not on my test server. How can I write a set of rewrite rules for the apache2 rewrite module on the test server to say "within the datavis.ca tree, interpret /papers, etc. to refer to /datavis/papers, etc."? I've read the documentation at http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html but I don't see how to accomplish what I want. TIA for any help on this
