htaccess Rewrite 301 with query string (parameters)

The overall URL has changed (the domain name has not changed), because it is the lamp environment, so you want to use htccess to do 301 redirects. Look up the internet, there are roughly two kinds of writing:

The code is as follows	Copy Code
1. #第一种 Redirect Permanent a.php b.php #或 Redirect a.php b.php #第二种 Rewriterule a.php b.php [l,r=301]

Rewriterule square brackets for modifiers, detailed flag please see here Http://httpd.apache.org/docs/2.4/rewrite/flags.html#page-header

My demand is to put view.php?iid=123 301 to/item/123.

How do you redirect a link with a query character? I tried the following two types but not available:

The code is as follows	Copy Code
1.Redirect ^view.php?iid= (d+) $/item/$1 2.RewriteRule ^view.php?iid= (d+) $/item/$1 [l,r=301]

Do htaccess rewrite rules, which 301 jump, found that the URL after the jump automatically added parameter transfer, that is, querystring.

such as the rules

The code is as follows	Copy Code
Rewriterule ^brot.* http://local.abc.com [r=301,l]

When this URL is encountered, the parameter is automatically taken

The code is as follows	Copy Code
Http://local.abc.com/brot/dsf?abc=1

will become such URLs:

The code is as follows	Copy Code
Http://local.abc.com/?abc=1

It was later found that query strings and files were required to be parsed separately, and the final wording was:

The code is as follows	Copy Code
1.RewriteCond%{query_string} ^iid= (d+) $ Rewriterule ^view.php$/item/%1? [l,r=301] #如果你的apache版本 >=2.4, you can use QSD flag #RewriteRule ^view.php$/item/%1 [L,R=301,QSD] QSD = qsdiscard Delete query string (new after Apache 2.4) QSA = qsappend Add Query string (This is more commonly used)

Attention matters

1. Query string use% to do reverse reference, the use of regular expressions and rewriterule is the same,%1 represents the first match except the original string, that is,%0 is iid=123,%1 123
2./item/%1 in the second article? I added a question mark later, because my Apache version is 2.2, only in 2.4 flag [QSD], add an empty query, you can get the results of the final item/123. If you don't use QSD or add "in the back"? "You will get the result is/item/123?iid=123, because 301 by default the query character is added to the

Among them, with the query string redirection is not easy to find, took me a lot of days, asked three forums, looked up n more than the Web page has no results. A friend also made a conclusion: "Unless you use the program, it is impossible to achieve this demand." Finally, search on google.cn with "Rewritecond%" for the keyword before the module mod_rewrite:rewriting URLs with Query strings and mod rewrite query string Problem found a clue, spent an afternoon to debug before successful. It's not easy.

I am not familiar with the mod_rewrite of Apache, some of the above content is also copied from others, the truth is not very clear, perhaps there are errors. Tips for friends who want to find mistakes and need improvement
