If a public website is powered by domino, it is often wished, that urls shared to social media, i.e. facebook. But this plattforms sometimes add url parameters to an url, if this is clicked. Facebook i.e. adds often ?fbclid=xxxx. This causes an error on the domino side. See also https://www.mindwatering.com/SupportRef.nsf/webpg/0857F020A5D9B04F85258524001BF3AE
The workaround is, to build all urls with ?open at the end, but that makes the url worst readable and it isn't possible in all cases. For instance, the domino blog template doesn't do that.
Domino should handle url parameters, that are no domino commands without throwing an error. I could be a database setting, if this parameters should throw an error or not.
Otherwise that is a big disadvantage to use domino as a server for public websites.
