mod-rewrite for URLs with extra characters after second slash

问题

How to return 404 error for all URL with extra characters after second / by htaccess.

e.g1:

http://www.example.com/blah-blah/ NOT Redirect (no extra characters after 2th /)

e.g2:

http://www.example.com/blah-blah/blah-blah Redirect to 404

e.g3:

http://www.example.com/blah-blah/blah-blah/ Redirect to 404

e.g4:

http://www.example.com/blah-blah/blah-blah/blah-blah Redirect to 404

e.g5:

http://www.example.com/blah-blah/blah-blah/blah-blah/ Redirect to 404

I tried this but not works with e.g3 & e.g5 (URLs ending with slash):

ErrorDocument 404 /404
RewriteBase /
RewriteRule ^[^/]+/.+ - [R=404,L]

回答1:

in order to redirect request only if there is some characters after second slash, you need to this rewrite rule

ErrorDocument 404 /404
RewriteBase /
RewriteRule .*/.+ - [R=404,L]

PS : when you're using a dash after regexp, it says to pass matches as it to filesystem.

EDIT : this pattern /.*/.+ matches with next example, but I forgot RewriteBase directive, so you need to remove first slash in pattern (I edit RewriteRule before)

• /blah-blah/ => Not match
• /blah-blah/blah-blah => Match
• /blah-blah/blah-blah/ => Match
• /blah-blah/blah-blah/blah-blah/ => Match

PS : You can use this tools, to check if your Rewrite works rewrite-rule-tester
