要求最大长度的IIS网址重写规则

Question

Based on this question: IIS Rewrite rule based on length param In windows server 2012 IIS, I would like to create a rule that check for the first parameter only for "n" max digits.

the answer proposed gives me an error,

<match url="product\\/([A-Za-z0-9]{4,100}+)\\/$" />

throws this error:

The expression contains a repeat expression (one of '', '?', '+', '{' in most contexts) that is not preceded by an expression.

someone else have an idea to resolve? Thank you

Answer 1

Your regexp should be like that: product\\/([A-Za-z0-9]{4,100})\\/$

You shouldnt use + if you specified length {4,100}
