篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了htaccess重写缓慢...更好的方法吗？相关的知识，希望对你有一定的参考价值。

我需要理清我的htaccess规则，因为我认为这是许多缓慢请求的原因......

我做了以下工作，但不确定是否有一个更好和有效的方式，而不是我现在正在做的方式...我之前真的不能改变结构，所以我必须这样做，改变我的方式将来结构更好。

我希望它是动态的，无需更改现有的URL，很多人都知道并且索引已经很久以前...而且，我不想永久重定向....

我的文件结构，（都在同一个文件夹中）

# If requested resource exists as a file or directory go to it
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule (.*) - [L]

RewriteRule ^sitemap.xml$ /sitemap.php [L]

# i dynamically change the page to AMP if /amp/pagename.php is accessed....
RewriteRule ^amp/(.*) /$1 [NC,QSA,L]
#i have added this one rule again as  the amp page for the home page is just /amp and the rule above with the trailing slash, didnt execute...
RewriteRule ^amp(.*) /$1 [NC,QSA,L]


RewriteRule ^car-price-(.*)-([0-9]+).php$ _car-price-mn-yr.php?gpimnt=$1&gpiyr=$2 [QSA,L]
    #car-price-january-2018.php   <- multiple urls: all months, years from 2009 to now... 

RewriteRule ^car-price-([0-9]+).php$ _car-price-yr.php?gpiyr=$1 [QSA,L]
    #car-price-2009.php <- yearly summary, many urls: 2009 till now.

RewriteRule ^car-price-([A-Za-z-]+).php$ _car-price-wildcard.php?_gpwilcvar=$1 [NC,QSA,L]
    #car-price-london.php <- similar to the above, making it confusing.... many cities...car-price-scotland.php  etc

RewriteRule ^car-price-([w-]+).php$ _car-price-wildcard.php?_gpwilcvar=$1 [NC,QSA,L]
    #gbp-rate-today-usa.php  <- i have different urls for e.g. cad.rate-today-usa.php, etc...

RewriteRule ^([w-]+).php$ _car-price-wildcard.php?_gpwilcvar=$1 [NC,QSA,L]
    #why-do-diesel-cars-cost-more.php  <-i have many articles that does not have a prefix or some sort to make this easier..

这些规则使我的网站加载时间延长了4秒....是否有更好的规则可以提供帮助，或者这是唯一的方法吗？

答案

结合/amp规则：

RewriteRule ^amp(/.+)? /$1 [NC,QSA,L]

作为一般的经验法则，避免使用.*匹配，因为*是贪婪的并且创造更大的回溯。

接下来，您可以在单个PHP文件中执行此操作，而不是使用单独的PHP脚本接受可选的gpimnt参数。如果不存在相同的值，则仅继续接收gpiyr值。这可以再次与条件gpwilcvar参数等组合，并减少您的URL匹配的模式总数。 PHP中的单个defined()（或isset()）调用比模式匹配更快。
