Azure Firewall - URL matching

Question

Azure Firewall - URL matching

Peter Stieber 180

Does www.contoso.com in targetUrl match www.contoso.com/?siteId=asd343s32kj343dce ?

Documentation mentions that it should match below examples

www.contoso.com

www.contoso.com/

The doc also mentions that

www.contoso.com/test

should match www.contoso.com/test?with_query=1

Can someone clarify ?

Hello Peter Stieber

Thanks for the reply!

As per the documentation,

User's image

www.contoso.com/test matches www.contoso.com/test?with_query=1.

The path /test is the primary factor for matching, and query parameters (like ?with_query=1) do not affect the match.

But,

User's image

Query parameters are not considered in the matching process for the base URL. Therefore, www.contoso.com/?siteabcabcabc does not match www.contoso.com or www.contoso.com/ because the presence of the query parameter changes the URL.

I hope this has been helpful!
