diffrence between .htm and .html

ive been told many things, but i do know that they both work but need to be specified as seperate

anyone know the origin of this?
im guessing one guy at w3 didn't just screw up

 

no difference as far as I know.. just depends how your webserver is set up to handle file extensions

 

They are identical.... the reason they both exist is a historic thing where one operating system (cannot remember which off hand) was only able to handle 3 letter file extensions hence why .htm exists

 

The obvious answer is in the spelling. There is an L or lack thereof. Other than that small difference, the two documents types are exactly the same. Both types may be used the same (on most host servers) and both will be rendered the same in browsers.
You should use HTM instead of HTML or vice versa... That depends on your preference. What looks better to you...

 

If I recall correctly, it was Windows 3.1 that had that problem.

 

both are same and act same. the reason it exist is coz of compatibilty issues

 

There is no difference between the two although I prefer .html for some reason. In fact, in my newest website, I am using .shtml so I can use SSI's. In other words, it doesn't matter what extension you have on your pages. My advice would be to stop worrying about issues like this and site down and write some quality content for your visitors,

 

It does matter what extension you have, or more accurately it matters on how you have your webserver set up to serve each extention.

You can have your server set up to have .sfas to go through the PHP framework but it must be configured as such.
