I have wordpress in a sub directory wpblog, and you would get it by typing "http://mysite.org/wpblog" into your browser.
I want to redirect from a page "http://mysite.org/test.html" to "http://mysite.org/wpblog/testtopic", where testtopic is a page in the blog.
I have permalinks enabled and allowed wordpress to write a .htaccess file into wpblog.
To do this I tried this:
I added a .htaccess file to the root directory (where test.html would be located) of this form:
RewriteEngine on RewriteRule ^test\.html$ /wpblog/testtopic
A request of the form "http://mysite.org/test.html" now goes to wpblog, but gives a '404 not found' - page, themed by my wordpress theme setting.
I can't work out exactly why this happens. To me it looks as if the wordpress generated .htaccess redirects EVERY url with the base wpblog to /wpblog/index.php, and then wordpress internally resolves which pages it should bring up. But why can't it resolve /wpblog/testtopic this way? (I can type "http://mysite.org/wpblog/testtopic" directly into the browser I get the correct page.) Or does wordpress try to make sense of "test.html" which in fact does not exist in wpblog.
I am mystified, and yes, I have searched the support forums.
(To be honest I don't have much hope to get this answered, given that there are loads of unanswered topics when you search for 'rewrite permalinks').
