Rewrite in .htaccess

[Frostie]

I can usually sort out any rewrites but I am struggling on this one, following the redesign of my pages and wondered how best to go about it would be;

All my pages have changed format so have changed from the following format;

http://www.mydomain.co.uk/company_nasty_term_company312.html

to....

http://www.mydomain.co.uk/company_seo_term_company312.html

So the stuff before and after "nasty_term" stays the same, just "nasty_term" has changed to "seo_term". I presume there are a few *'s a few ^'s and a few $1 or $2 to be added in the rule, but I am scuppered if I can get it to work.

Can anyone shed any light? The best I could come up with (but doesnt work) is;

RewriteRule ^.*_nasty_term_*.html http://www.mydomain.co.uk/$1_seo_term_$2.html

I need to change it to help with the Search Engines that have the old "nasty_term" in their indexes.

RewriteRule ^(.*)_nasty_term_(*.)html$ http://www.mydomain.co.uk/$1_seo_term_$2.html [L]

Causes 500 internal errors.

Thanks anyway for suggestion.

Hi M8,

You are getting the error 500 because the values of $1 & $2 are not getting passed.

How are you picking up the values of $1 & $2 ? and what did your old *nasty_term htaccess rule look like?

you must have a dynamic page that picks the vars up?

[Frostie]

Yeah I have a rewrite rule that gets dynamic pages and chucks them as static html's.

The old HTMLs have been indexed so I am just trying to change these. The rewrite from dynamic to static is working fine under the new seo_term

Confusing myself now

Gottcha you want to redirect then not re-write to tell the search engines you moved it?

 redirect 301 (.*)_nasty_term_(*.)html http://www.mydomain.co.uk/$1_seo_term_$2.html

[futureweb]

You want a $ on the end of the nasty.html$ soz

Still no joy

I will PM you the htaccess file because its probably the way I am explaining it
