Hello,


I wrote this to the site admin (Jan Knepper) too. Walter and I are 
trying to set up the digitalmars.com server such that all request for 
pages under digitalmars.com/d/2.0/ go to the corresponding file in 
d-programming-language.org/.

I experimented on my own website and here is the appropriate .htaccess 
rule that works:

RedirectMatch ^/d/2\.0/(.*) http://d-programming-language.org/$1

With this, e.g.

http://digitalmars.com/d/2.0/phobos/std_algorithm.html

should automatically redirect to

http://d-programming-language.org/phobos/std_algorithm.html

When Walter put that .htaccess under the directory serving /d/2.0, we 
got an internal server error.

Do you know what the issue might be? Is there some mistake we're making?


Thanks,

Andrei

Apache rewriting is the hardest thing in the world.


But I'd try putting a [R] at the end of that redirect line
and if it fails, check the error log.

tail /var/log/httpd/error_log

or whatever it is on your box. Sometimes there's something helpful
in there.

The [R] applies to RewriteRule, not RedirectMatch.

Walter, could you please take a look at the error log. Thanks!

I don't know what is the issue with RedirectMatch, but usually I use 
Apache's rewrite engine for redirects. That'd be:

	RewriteEngine On

	RewriteRule ^d/2\.0/(.*)$ http://d-programming-language.org/$1 [R=301,L]

R=301 gives you a permanent redirect (HTTP response 301), L makes sure 
no other rewrite rule are applied.

Turns out all .htaccess use was disabled by the admin (Jan Knepper). He 
added the redirect straight to the config file of the server.

Now everything with the prefix http://digitalmars.com/d/2.0/ or 
http://www.digitalmars.com/d/2.0/ should redirect to the respective page 
on d-programming-language.org.

Let us know how that works!


Thanks,

Andrei

It seems to be working quite nicely.
My old bookmarks now redirect to exactly what they should.

Thank you.
