I've generated an xml sitemap for the first time and am reviewing it before I upload it to Google.

All of the urls are https:// instead of http://

Is there a reason for this? If I enter the url of a category into the browser as:
it redirects to a dynamic page url with no https//:
If I enter the url as:
it goes to the category page directly and url in the browser stays the same:
Is there a reason to have all your urls in the sitemap start with https:// ?

If not, I'll probably change them to http:// because things seem to load faster.

Thanks.

Hello Will,

It's working so it looks like google doesn't care but I'm going to report it and get it changed regardless.

Yeah, it didn't seem to matter, but thought I would check to make sure.

Thanks.
