最后两行.htaccess导致错误

Question

我的.htaccess文件的最后两行导致我得到一个＆＃34;太多的重定向＆＃34;错误。如果我删除最后两行中的一个或另一个，它可以正常工作。但是，我需要两者兼顾。

RewriteEngine On
RewriteBase /calc/


RewriteRule ^c-(.*)$ catpost.php?id=$1 [L]
RewriteRule ^ec-(.*)$ eventcatvenue.php?id=$1 [L]
RewriteRule ^a-(.*)-(.*)$ archives.php?month=$1&year=$2 [L]
RewriteRule ^e-(.*)-(.*)$ event-dates.php?month=$1&year=$2 [L]
RewriteRule ^e-(.*)-(.*)$ event-dates.php?month=$1&year=$2 [L]
