关于 ISAPI_Rewrite 请高手指点
# Helicon ISAPI_Rewrite configuration file
# Version 3.1.0.50
RewriteEngine On
RewriteCompatibility2 On
RepeatLimit 200
RewriteBase
# unsupported directive: [ISAPI_Rewrite]

RewriteRule ^.*(?:global.asa|default\.ida|root\.exe|\.\.).*$ .[F,I,O]
RewriteRule ^/([0-9,a-z]*).html$ /news/news_index.asp\?id=$1
请问
?id=$1 中 $1 一定是数字吗?
