    ..html was the original extension for HTML pages on Unix Web hosting machines.
    ..htm was created by Windows/DOS because of it's requirement for 3 character extensions.
    .htm is kind of obsolete, but either .html or .htm is still completely functional and acceptable
    the only problem is if the server is only configured to look for index.html and not both .html and .htm which could result in an
    unwanted directory listing

    The technical difference that the additional letter will make to an http server (a "web server") is minimal. Usually, a server will use a file's extension to figure out what MIME type to send back to the requesting client. Most servers are configured by default to send back the text/html type when the requested file ends in an htm or html extension. This can be changed by the server's administrator(s) in such a way that one of the above extensions returns a different MIME type then the other, however, this is not a very common practice.

    It is a common misconception that a file ending in an htm extension had to have been created on a DOS/Windows 3.x platform. This is because those operating environments limit filenames to a 3 letter extension. However, it is very simple to create a file with a 3 letter extension on most other platforms, as well. Even those that allow longer file extensions

    one site says it's a 'common misconception'
    and it's taken as fact and used as a ' you're wrong' approach to counter people who know what they are talking about, i put in your profile because it shows that you are knowledgeable in the field and rupert has a lot of experience, so one site statemetn is used to refute several statements that htm was dos/3.1 and html was unix, i'll go with the 3.1/unix explanation as i have more trust for those who have given me that knowledge

    --- just my 2 cents

    they are pretty much the same thing. It will not affect your code in any way.
