IIS rewrite URL in asp.net goes to into infinity loop

Question

I just need to create a rule in my web config file to rewrite all URLs to given into rule

ex: url/services/presentations-evenementielles to url/Services/Presentations-Evenementielles

This is all made for SEO purposes to avoid duplicates.

<rule name="ProductionRule2" stopProcessing="true" patternSyntax="ExactMatch" >
                <match url="^/productions/xyz" ignoreCase="true" />
                <action type="Redirect" url="Productions/XYZ" redirectType="Permanent"/>
              </rule>

Above code its gives me infinite loop error.

Answer 1

There was some mistakes with your rule

1.You were trying to use "^" in an exact match rule. Please set it to regular expression

2.You are trying to use "/" in match url. The match url part of domain/productions/xyz is productions/xyz instead of /production/xyz.

3.You are enabling ignore case when you redirect URL to itself.

So please try to modify the rule like this

<rule name="ProductionRule2" patternSyntax="ECMAScript" stopProcessing="true">
                <match url="^productions/xyz" ignoreCase="false" />
                <action type="Redirect" url="Productions/XYZ" redirectType="Permanent" />
              </rule>

Update:

Please modify the rule like this

<rule name="ProductionRule2" enabled="true" patternSyntax="ECMAScript" stopProcessing="true">
                <match url="^Productions/XYZ" ignoreCase="false" negate="true" />
                <action type="Redirect" url="Productions/XYZ" redirectType="Permanent" />
                    <conditions>
                        <add input="{ToLower:{URL}}" pattern="/productions/xyz" />
                    </conditions>
              </rule>

And this is working on my side

Please remember to clean browser cache when you test the rule.And the URL should be prODuctions/Xyz instead of prODuction/Xyz.
