mod_rewrite的URL编码已经urlen codeD查询参数 - 任何方式禁用此？ [英] mod_rewrite urlencoding an already urlencoded querystring parameter - any way to disable this?
问题描述
我们有一些非常基本的mod_rewrite的规则：
we have some very basic mod_rewrite rules:
RewriteRule ^something.swf$ http://www.newdomain.com/something.swf [R=302,L]
mod_rewrite的接缝来完成其工作，并且如果用户正在访问：
mod_rewrite seams to do its job, and if the user is accessing:
something.swf？参数=值，它被正确重定向到<一个href=\"http://www.newdomain.com/something.swf?param=value\">http://www.newdomain.com/something.swf?param=value
something.swf?param=value, it is redirected correctly to http://www.newdomain.com/something.swf?param=value
问题是在这种情况：
www.olddomain.com/something.swf?param=URL_EN$c$cD_VALUE
www.olddomain.com/something.swf?param=URL_ENCODED_VALUE
什么最终发生的是mod_rewrite的采取它在它的自我重新urlen code中的查询字符串参数
what ends up happening is mod_rewrite takes it upon it self to re-urlencode the querystring param
所以用户是最终得到的是：
so what the user is end up with is:
www.olddomain.com/something.swf?param=URL_ENCODED_VALUE
重定向到
www.newdomain.com/something.swf?param=URL_ENCODED_VALUE_OF_URL_ENCODED_VALUE
所以我们最终采用了双层urlen codeD值。 boourns！
so we end up with a double-urlencoded value. boourns!
虽然我明白，我们可以做一个\\？（。*）...？$条规则对于这一点，我在想，必须有办法告诉了mod_rewrite不要将urlen code中的查询字符串PARAMS .. 。我们想避免使用2规则，因为有效路径是：
while i do understand we could make a \?(.*) ... ?$1 rule for this, i am thinking there must be a way to tell mod_rewrite NOT to urlencode the query string params... we would like to avoid using 2 rules since valid paths are:
something.swf (no query string)
和
something.swf?someparams...
所以啊，idealy ......只是告诉mod_rewrit：请，没有查询字符串参数...只是直接中继的URL编码，以通过R新的URL，302
so yea, idealy... just tell mod_rewrit: please, no urlencoding of querystring params... just direct passthru to the new url via r,302.
人？
谢谢！
推荐答案
做到这一点的方法是通过NE（无路可逃）paramater。
the way to accomplish this is via the NE (no escape) paramater.
RewriteRule ^something.swf$ http://www.newdomain.com/something.swf [R=302,L]
其实应该读
RewriteRule ^something.swf$ http://www.newdomain.com/something.swf [R=302,NE,L]
这将迫使mod_rewrite的给所有的查询字符串值，因为他们，没有做任何编码/逃脱。
this will force mod_rewrite to leave all query string values as they are, without doing any encoding / escaping.
一样容易认为：）
