.htaccess正则表达式 - “关键字”样式重定向 - 语法？

Question

Problem: inbound outdated links to products that have been discontinued. Challenge: many variations with additional keywords, subcategories, etc.

Examples:

• /somecategory/cool-widget-OLDNAME
• /special_sale_on_OLDNAME_items
• /category/subcat/subsubcat/morestuff/weird_keywords_OLDNAME

Needed solution: something that will catch the keyword "OLDNAME" *regardless of what it's surrounded by, and redirect to a specific page.

E.g. "RewriteRule ??????? OLDNAME ?????? http://www.example.com/newpage [L,NC,R=301]

The bold part is what I need help with.

Thanks in advance!

Answer 1

Try

RewriteRule  ^.*(OLDNAME|ANOTHEROLDNAME).*$ http://www.example.com/discontinued [L,NC,R=301]

it lookups any given word at any position in the given url.
