[英]What does this apache rewrite means?
RewriteCond %{QUERY_STRING} (.*)\?mem=stats$
RewriteRule ^/(.*)$ http://X.X.X.X/$1?%1 [P,L]
If the request is /asdf?mem=stats
, will it rewrite to /asdf?mem=stats?asdf
? 如果请求是/asdf?mem=stats
,它将重写为/asdf?mem=stats?asdf
吗?
since $1
is asdf?mem=stats
and %1
is asdf
??? 因为$1
是asdf?mem=stats
而%1
是asdf
???
The %{QUERY_STRING}
variable contains the query string without the leading ?
%{QUERY_STRING}
变量包含查询字符串,但不包含前导?
(or anything before it), so %1
will never contain part of the request before query string. (或其之前的任何内容),因此%1
绝不会在查询字符串之前包含请求的一部分。
If you enable mod_rewrite logging by adding LogLevel rewrite:trace6
to your VirtualHost configuration, you will see this for your RewriteCond and /asdf?mem=stats
request: 如果通过在VirtualHost配置中添加LogLevel rewrite:trace6
来启用mod_rewrite日志记录,您将在RewriteCond和/asdf?mem=stats
请求中看到以下内容:
... RewriteCond: input='mem=stats' pattern='(.*)\\?mem=stats$' => not-matched
Also, in your RewriteRule
, pattern will be matched against the part of the URL after the hostname and port, and before the query string. 另外,在您的RewriteRule
,模式将与主机名和端口之后,查询字符串之前的URL部分匹配。 Therefore $1
will, even on wildcard match, not contain the query string part of the request. 因此,即使通配符匹配, $1
也将不包含请求的查询字符串部分。 You can see that in log as: 您可以在日志中看到以下内容:
... applying pattern '^/(.*)$' to uri '/asdf'
