Hi Peggy Jackson,

In web addresses, the domain name portion is normally case-insensitive, so browsers often display or process it in lowercase without affecting access. For example, MyWebsite.com and mywebsite.com should resolve to the same site.

To help identify the cause, could you provide:

Whether the capitalization is being changed in the domain name or in the page/path after the domain.
The specific error message you receive when the site fails to load.
Whether the same issue occurs in another browser such as Chrome or Firefox.

If the affected portion is the path (for example, /MyFolder/MyPage), the website or server may be configured to treat uppercase and lowercase characters differently, which would be a website-side issue rather than an Edge issue.

Thank you.

The error occurs with RootsMagic, which apparently requires the capitals to remain in the domain name. When I try to load it, it is these two capitals which are changed arbitrarily.

I get a similar error message in Chrome.

Hi Peggy Jackson,

Domain names are not case-sensitive, so it seems your problem is related to another reason, such as server configuration.
