Weirdness: I have a Powershell cmdlet here that seems for all the world to be choking on a wildcard character. I didn't know that was possible, to be honest--I mean, this thing says it doesn't actually accept wildcards, so whatever...
Yeah, the request was actually being denied by the website and, as a result, the cmdlet was returning that nonsense about wildcard paths. I think that's because the path did, in fact, include a powershell wildcard (that is, the ? -- which is definitely legal in an HTTP request, believe it or not :P).
Using wildcards such as the asterisk (*) will alter how the exclusion rules are interpreted. See the Use wildcards in the file name and folder path or extension exclusion lists section for important information about how wildcards work.
You can use the asterisk *, question mark ?, or environment variables (such as %ALLUSERSPROFILE%) as wildcards when defining items in the file name or folder path exclusion list. The way these wildcards are interpreted differs from their usual usage in other apps and languages. Make sure to read this section to understand their specific limitations.
You can also manually add Wildcard Domains to a certificate request. A wildcard domain takes the form *.yourdomain.com and the resulting certificate would cover anything.yourdomain.com, but it will not cover nested subdomains i.e. www.anything.yourdomain.com. You will also need to add the top level yourdomain.com to the certificate if you wish to cover requests to that domain directly.
You cannot mix certificate requests for a Wildcard and a first-level subdomain (e.g. in a request for *.yourdomain.com and www.yourdomain.com, you should remove the www.yourdomain.com as it's already covered by the wildcard domain).
HTTP validation requires that your domain be a publicly accessible website with an http service on TCP port 80 (even if that's only for http validation purposes). You cannot use http validation if you need a wildcard certificate.

Yes, I saw that a few weeks ago when I was checking this script again for updates to it. I think I will skip wildcard addresses, because they are not revolving. Or, if that works, try a random name in that just to check if it will give a response.
My primary use case in writing this concerned distribution of commercially purchased SSL certificates; particularly something like a wildcard cert which needs to be distributed to many nodes and will be need to be updated periodically as renewals happen.
A wildcard certificate is a certificate that includes one or more names starting with *.. Browsers will accept any label in place of the asterisk (*). For example, a certificate for *.example.com will be valid for www.example.com, mail.example.com, hello.example.com, and goodbye.example.com.
However, a wildcard certificate including only the name *.example.com will not be valid for example.com: the substituted label can not be empty. If you want the certificate to be valid for example.com, you also need to include example.com (i.e. without the *. part) on the certificate.
Additionally, the asterisk can only be substituted by a single label and not by multiple labels. For example, the name hello.goodbye.example.com will not be covered by a certificate including only the name *.example.com. It will be covered however, by *.goodbye.example.com. Note that a wildcard name can not contain multiple asterisks. For example, *.*.example.com is not valid.
This rule monitors for the execution of a set of linux binaries, that are potentially vulnerable to wildcard injection, with suspicious command line flags followed by a shell spawn event. Linux wildcard injection is a type of security vulnerability where attackers manipulate commands or input containing wildcards (e.g., *, ?, []) to execute unintended operations or access sensitive data by tricking the system into interpreting the wildcard characters in unexpected ways.
As well as literals and capture braces for field values, URL path templates canuse wildcards to indicate that anything in this part of the URL should becaptured. The shelf notation used in the preceding example is actually ashortcut for shelf=*. You can find out more about the rules for pathtemplates in theHTTP rule reference.
If you want to rewrite paths to remove the path prefix, you can accomplish this by using the wildcard pattern. The source address would contain the path prefix, but the target address would omit the prefix as seen in Figure 2.
Meanwhile, a wildcard certificate secures a single domain and any related subdomains. However, a multi-domain wildcard certificate is the better choice if you have various websites with numerous subdomains.
For example, you can get a free SSL certificate with Kinsta thanks to our Cloudflare integration, which even supports wildcard domains. All you need to do is purchase a hosting package, such as managed WordPress hosting.
Upgrading to IIS 7 should be rather transparent, unfortunately that is not the case when it comes to URL rewriting as we knew it from IIS 6. In IIS 6 all we had to do was to add a wildcard mapping making sure that all requests went through the ASPNET ISAPI process. After this was done, one could create a global.asax file that would either pass requests directly through or rewrite the URL based on an internal algorithm.
