Pages redirection 301

Moving to new pages

[axelf]

Greetings,
Please help.
I need a redirection rule 301 - moved permanently (for search engine).

My current links looks like:
www.mydomain.com/postt859.html

and I need it to redirect to new:
www.mydomain.com/forum/viewtopic.php/t,859

The number 859 is variable.

What code I need to insert in .htaccess? I have no idea how to do it myself.
Many thanks in advance.

If you are doing this for the search engines, I would say that it would not be very good idea considering that www.mydomain.com/postt859.html URL is much better than www.mydomain.com/forum/viewtopic.php/t,859 as far as Search engine's crawling is considered.

Things to consider. Is the new site on the same domain? on the same host?

Have you changed to a new software package to run the site? Has the internal filepath changed as a result of that?

What internal filepath inside the server is the content really located at? Please provide details of the internal filepath (Note: a filepath is NOT a URL).

I don't understand why you want to redirect from a 'simple' URL to a 'complex' URL. Maybe you are needing a rewrite instead. Please carefully answer *all* of the above questions.

There are several thousand prior examples of the code you need here in this forum. Do not even think about code until we have gotten the exact requirements defined first.

Its the new site on the same domain and host.
I am changing the software package (CMS + upraged forum). I changed the dir for forum from: /home/user/www.mydomain.com/modules/Forum to /home/user/www.mydomain.com/forums

I know that this new URL is complex, but better I cant get with this CMS (Joomla,Jfusion,PHPBB3).
It would be perfect to stay the same, only with added dir like: www.mydomain.com/forum/postt859.html but I think its not possible.
The old rule was: RewriteRule ^post(p¦t)([1-9][0-9]*).* modules.php?name=Forums&file=viewtopic&$1=$2

For the begining it would be much better to do just the R301, as I mention at the first post, due to lost links from search engines.

The answer to your direct question is

RewriteRule ^post([a-z])([0-9]+)\.html$ http://www.example.com/forum/viewtopic.php/$1,$2 [R=301,L] 

This assumes that you've already got other working mod_rewrite code in the .htaccess file.

Place all redirects ([R=301,L]) ahead of all internal rewrites ([L]) and put the two groups of rules in order from most-specific to least-specific patterns and conditions.

See the references cited in our Apache Forum Charter for more information.
