Question

I’m trying to write URLs inside my Web Applications both In- and Outbound using IISs URLRewriter like so:

www.domain.net/SomeSite.aspx to www.domain.net/SomeSite using this RegEx for Inbound:

^([A-Za-z0-9]+)([\?A-Za-z0-9=&]+)?$, much to my surprise, this actually works, also for URLs such as www.domain.net/SomeSite.aspx?abc=1 => www.domain.net/SomeSite?abc=1 using this Rewrite Action: {R:1}.aspx?{R:2}

But now, for Outbound, I’d like to have the same effect so the user actually sees www.domain.net/SomeSite even though my webapplication might be referencing ~/SomeSite.aspx internally.

I use the following RegEx for that:

^([A-Za-z0-9]+).aspx([\?A-Za-z0-9=&#]+)?$ and rewrite the URL like so: /{R:1}{R:2}

In general this works, alas, it does not for e.g. Response.Redirect executed in CodeBehind and neither does it work for PostBackUrls from asp:Buttons.

Does anyone have any idea how to rewrite this outbound rule so it actually catches every link regardless of how I referenced it?

Thanks,

Dennis

Edit:

Some examples since I suppose I wasn’t quite as clear as I thought:

User enters www.domain.com/Login in Browser, Inbound-Rule catches and redirects to www.domain.com/Login.aspx yet shows /Login in the Address Bar, this behaviour is fine.

However, when I click on i.e. an asp:Button with PostBackUrl Login.aspx the Address Bar will show Login.aspx instead of the desired Login, how to get exactly this behaviour?

As it turns out, the only thing I needed to do was add an Inbound Redirect Rule and set stopProcessing to true for both rules. Here’s the result:

<rules>
        <rule name="Clean URL" stopProcessing="true">
            <match url="^([A-Za-z0-9]+)([\?A-Za-z0-9#=&amp;]+)?$" />
            <action type="Rewrite" url="{R:1}.aspx{R:2}" />
        </rule> 
        <rule name="CleanTest" stopProcessing="true">
            <match url="^([a-z0-9/]+).aspx([a-zA-Z0-9\?#=&amp;]+)?$" />
            <action type="Redirect" url="{R:1}{R:2}" />
        </rule>
</rules>
