I tried that but nothing gets written in the log. Other rules do, like this one for ex.
<rule name="Rewrite to article.aspx">
<match url="^article/([0-9]+)/([_0-9a-z-]+)" />
<action type="Rewrite" url="article.aspx?id={R:1}&title={R:2}" />
</rule>
So I believe I have set the tracing Ok.
I simply get the error "Server not found...".
After that I returned the following line to the DNS zones configuration:
* A xxx.xxx.xxx.xxx
Without it, there were problems, for ex. pop.domain.com didn't work anymore.
No I am getting the IIS welcome page again for the subdomain rule and nothing gets written in the logs. The Article rule works fine.
As if this request never gets to the point where the rule should be applied. Could there be something else in the IIS configuration that would block subdomain requests?
