mod_rewrite 在每个重写规则之后评估 {REQUEST_FILENAME} 吗？
情况如下：
RewriteEngine On
RewriteBase /app/webroot/
RewriteRule ^(.*)$ $1 [QSA]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
第二条规则的 RewriteConds 是否使用第一个 RewriteRule 的结果？
例如，如果我请求 /onestaticfile.txt 并且该文件实际上存在于 /app/webroot 中，如何确保最终网址为 /app/webroot/onestaticfile.txt< /code> 而不是 /app/webroot/index.php?url=onestaticfile.txt ？
Here is the case :
RewriteEngine On
RewriteBase /app/webroot/
RewriteRule ^(.*)$ $1 [QSA]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
Does the RewriteConds for the second rule use the result of the first RewriteRule ?
For instance, if i request /onestaticfile.txt and that file actually exists in /app/webroot, how to be sure that the final url would be /app/webroot/onestaticfile.txt instead of /app/webroot/index.php?url=onestaticfile.txt ?

将评估第二条规则的 RewriteConds。但由于
onestaticfile.txt存在，它将无法通过 !-f 测试，并且不会应用第二条规则（因此最终网址将是：/app/webroot/onestaticfile.txt< /代码>）。同样，如果onestaticfile.txt不存在，则将应用第二条规则。无论哪种情况，当应用规则时，都会发生内部重定向，并且整个事情会随着重写的 URI 再次发生。但第二次不会更改基本 URI（没有查询字符串），因此第二次不会发生任何事情。
如果第一条规则的方括号中有一个 L，则永远不会应用第二条规则，因为重写始终会在第一条规则处结束。
The RewriteConds for the second rule will get evaluated. But since
onestaticfile.txtexists, it will fail the !-f test and the second rule won't be applied (so final url will be:/app/webroot/onestaticfile.txt). Likewise, ifonestaticfile.txtdoesn't exist, the 2nd rule would get applied.In either case, when the rule is applied, an internal redirect happens and the whole thing happens again with the rewritten URI. But the 2nd time around doesn't change the base URI (without the query strings) so nothing happens the second time around.
If you had an L in the square brackets of your first rule, the 2nd rule would never be applied because rewriting will always end on the first Rule.
