“+”字符导致问题 IIS URL 重写

Question

I have the URL that I want to set a redirect to in IIS.

Current URL: portal/en_us/apps/app+doc

New URL: apps/newapps

Not working with

<rule name="From portal/en_us/apps/app+doc" stopProcessing="true">
    <match url="^portal/en_us/apps/app+doc$" ignoreCase="true" />
    <action type="Redirect" url="https://domain1123.com/apps/newapps" />
</rule>

results in a 404 error

Answer 1

Referring to a reference guide , we'll see that + is defined as working like this:

Matches previous element one or more times.

That means that this expression:

^portal/en_us/apps/app+doc$

Will match an entire string containing:

• portal/en_us/apps/appdoc
• portal/en_us/apps/apppdoc
• portal/en_us/apps/appppdoc
• portal/en_us/apps/apppppdoc

And so on.

To actually match a literal + , you need to escape it using \ :

^portal/en_us/apps/app\+doc$

Now it is treated as a literal + and not interpreted as "one or more p characters".

I have added allowDoubleEscaping

<system.webServer>
     <security>
          <requestFiltering allowDoubleEscaping="true" />
     </security>
</system.webServer>

You can try to encode the "+" character first, and then redirect.

You can use this link to code: https://www.urlencoder.org .
