我知道仅在此站点上就曾多次问过这个问题，但是浏览相关帖子后，我找不到解决方案。尝试删除域后的多个尾部斜杠。以下mod_rewrite表达式似乎适用于http://www.domain.com//path1///path2////之类的URL，但不适用于domain//
DirectorySlash Off
RewriteEngine on
# Canonical fix
RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301]
RewriteRule ^/main.do http://www.domain.com/ [R=301,L]
RewriteRule ^/index.jsp http://www.domain.com/ [R=301,L]
# Remove bogus query strings
RewriteCond %{query_string} q= [NC]
RewriteRule (.*) http://www.domain.com/$1? [R=301,L]
# Remove multiple slashes after domain - DOESN'T WORK!!!
#RewriteCond %{REQUEST_URI} ^//+(.*)$ [OR]
#RewriteCond %{REQUEST_URI} ^(.*/)/+$
#RewriteRule / http://www.domain.com/%1 [R=301,L]
# Remove multiple slashes anywhere in URL
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . %1/%2 [R=301,L]
# Externally redirect to get rid of trailing slash except for home page, ads
RewriteCond %{REQUEST_URI} !^/ads/
RewriteRule ^(.+)/$ $1 [R=301,L]
最佳答案
无法复制。即使关闭DirectorySlashes，域之后也不会将多余的斜杠传递给mod_rewrite －我尚未检查是删除了斜杠还是Opera还是Apache。但是否则，一切正常:
RewriteBase /
RewriteCond %{REQUEST_URI} ^//+(.*)$ [OR]
RewriteCond %{REQUEST_URI} ^(.*/)/+$
RewriteRule .* http://domain/%1 [R=301,L]
要求http://localhost//abc/b//

注意:考虑不对主机进行硬编码:
RewriteCond %{HTTP_HOST} !=""
RewriteCond %{REQUEST_URI} ^//+(.*)$ [OR]
RewriteCond %{REQUEST_URI} ^(.*/)/+$
RewriteRule .* http://%{HTTP_HOST}/%1 [R=301,L]
另请注意，内部的“//”未被替换。您将添加另一个规则来替换内部斜杠。
新编辑:
好的，这似乎可以防止URL以//开头或结尾:
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} !=""
RewriteCond %{THE_REQUEST} ^[A-Z]+\s//+(.*)\sHTTP/[0-9.]+$ [OR]
RewriteCond %{THE_REQUEST} ^[A-Z]+\s(.*/)/+\sHTTP/[0-9.]+$
RewriteRule .* http://%{HTTP_HOST}/%1 [R=301,L]
