Updating multiple sites with the same content

[skyvia]

I have one page of content (a links page describing all my sites) that appears on all my sites which are all on the same server. Right now, if I make a change or add a new site, I need to edit each page on every site. I would like to be able to edit one page and have the changes appear on all sites. I assume I need some sort of script to do this but I don't know what language or even if I do need a script. Is this even possible? Any ideas of where to start... or where to start looking?

You could have a seperate database which contains the list of links, and all the sites grab the list from there. Or you can create a directory with one file in which contains the links, and add it as a virtual directory to all the other sites.

If you have dreamweaver, you can implement library and include function to all the html page. Alternatively, you need convert the entire site to server language, which asp, php, jsp
