putting a web server on my phone that generates a page with a map of location?

[JhnGC]

I've searched the internet for the past 2 days, and still can't find a concise explanation of what i want do. I have a host that redirects to my rooted phone, now i want my phone to serve a page that shows the phone location on a map. A long time ago a read a guide but can't find it now. I know there are apps that do this, but i want to try on my own (well, with your help). Thanks for pointing me in the right direction if you can. What sever app, and how to configure it?
