about seo url

[ipghmagnet]

Hello all:
I found some website: they show theire web url
For example:
../aboutus.html (it is our common ways)
But i found some else they show like below:
../aboutus  (without. html).
In this new way, it seems better to rank higher..

What is your idea? It is possible for elxis ?

Why it is better without the .html part?

URLs are component specific. Each task is controlled differently. Elxis uses URLs with and without .html at the end depending on the task. The general idea is the URLs to mimic a static html site. For articles we use .html at the end to mimic an HTML document. For categories we use a slash / to mimic a folder. For ajax tasks and other internal requests you use nothing eg example.com/something
