is there a maximum of 301 redirects

[tuffy]

have aprox. 50k, dynamic pages in the format of www.mysite.com/product.php?part=1 that i want to permanently redirect to their static siblings in format of www.mysite.com/product-part-1.php.

my question: is there a maximum number of 301 redirects that can be placed in .htaccess ?

my concern is that googlebot pulls both dynamic and static & would prefer to not have duplicate pages.

any insight would be helpful.

thanks,

There is no limit, though a very large number of rules might impede server efficiency.

If there is a "simple relationship" between the two URLs, then you might only need *one* rule.

RewriteRule allows you to do a lot more than Redirect or RedirectMatch.

Any rule should also fix the domain canonicalisation issues within the same rule.

g1smd - thanks for the response. unfortunately, there is not a "simple relationship" between the two urls.

Rewrite all "old" requests to a script. Have the script look up the new URL in a database and force the redirect.
