Need help updating multiple sites at once?

Hi guys, I had this question, but I wasn't sure if this is the right place to post. I develop websites and have a few domains that basically have the same exact content for now. But somtimes I want to make changes to the main site and then have the other sites with the same content change without me having to reupload the HTML files. Is there a way to do this? I'm not sure if this is something I could do with CSS STYLE SHEETS.

Thanks, :wave

 

Well if the content is never changing then you could use a single CSS file that they all use. The browser can take a CSS file from another domain with no issues. That would effectively change the colors/style of all the pages tied to that CSS file but if you need to change the content too then it wouldn't be done as easily. If you have some specific questions I'd be happy to help.

 

If you don't mind redirecting users, you can use javascript's location object or the meta refresh tag or the location header to automatically go to the main domain from the others. Also, I find the dos ftp command to be fairly effecient in updating several sites, if you don't mind typing console commands. (Actually, you could probably make a script to run it.)
