Which .htaccess redirect rule(s) would one use to create all of the following forwards?

• http://old.io -> http://old.io/-> http://old.io/abc -> http://old.io#def -> http://old.io/abc#def ->

• http://old.io --> http://new.com?pa=va
• http://old.io/ --> http://new.com/?pa=va
• http://old.io/abc --> http://new.com/abc?pa=va
• http://old.io#def --> http://new.com#def?pa=va
• http://old.io/abc#def --> http://new.com/abc#def?pa=va

. . .并包含其他任意参数:

. . . and include any other arbitrary parameters:

• http://old.io?p2=v2 -> http://new.com?pa=va&p2=v2
• http://old.io/?p2=v2 -> http://new.com/?pa=va&p2=v2
• http://old.io/abc?p2=v2 -> http://new.com/abc?pa=va&p2=v2
• http://old.io#def?p2 = v2 -> http://new.com#def?pa = va& p2 = v2
• http://old.io/abc#def?p2=v2 -> http://new.com/abc#def?pa=va& ; p2 = v2

• http://old.io?p2=v2 --> http://new.com?pa=va&p2=v2
• http://old.io/?p2=v2 --> http://new.com/?pa=va&p2=v2
• http://old.io/abc?p2=v2 --> http://new.com/abc?pa=va&p2=v2
• http://old.io#def?p2=v2 --> http://new.com#def?pa=va&p2=v2
• http://old.io/abc#def?p2=v2 --> http://new.com/abc#def?pa=va&p2=v2

推荐答案

因此，基本上，您需要在任何可能构造的URL的查询字符串中添加pa=va:

So, basically you need to add a pa=va to the query string of any possible constructed URL:

RewriteEngine on
RewriteBase /

# Check if the host matches old.io,
# You might want to add www\. to that.
RewriteCond %{HTTP_HOST} ^old\.io

# Rewrite URLs with empty querystring
RewriteCond %{QUERY_STRING} ^$
RewriteRule ^(.*)$ http://new.com/$1?pa=va [L,R]

# Rewrite URLs with non-empty querystring    
RewriteCond %{QUERY_STRING} ^.+$
RewriteRule ^(.*)$ http://new.com/$1?pa=va&%{QUERY_STRING} [L,R]

请注意，锚点哈希部分需要排在查询字符串的之后.

Note that the anchor hash part needs to come after the query string.

如果愿意，可以对其进行在线测试.
