Step 1. Install a web server on your LAN.
Step 2. Edit the HOSTS file so that web site is directed to your web server.
Step 3. Create the pages you want to show at your web server.
Mildly advanced so all the steps won't fit here but the 3 steps here are a guide to making it happen.
I am trying to replace a webpage that I do not own with an edited version on my local network at home. I want my edited version to appear in place of the other page when the link to it is clicked, in essence redirecting from the original to my edited. I have some layman knowledge but detailed help/instructions would be preferred. Thanks!
