@burnout426 Something is wrong... the cache is not refreshing. I got the alert but now do not want it. So I commented it out in my code, saved the file and uploaded it to my server. When I click the Google Map I DO get the alert which now is not wanted. I tried the Private page and it did NOT have the alert. I don't want to have to delete all my settings every time I make some change to my site and upload it. Can you think of any setting that I should be using to correct for this situation? Thanks! A fresh rabbit hole I suspect...

After making a change on the server, you can hit ctrl + F5 on the page to load the fresh version of the page.

While testing the site at least, you can have the server send:

Cache-Control: no-cache, no-store, must-revalidate

in the response header to the client if you want.

@burnout426 Works like a charm! Is there a way to send this command:

On a cell phone - both Android and iPhone?
Via JavaScript code from within the webpage so when it loads it runs?

@burnout426 tried to get the Cache-Control command to work in the header of my webpage and couldn't get it to work. One did nothing and another try rendered a blank white page. Do I do this from within the webpage on the server from the HEAD section and should it be in a JavaScript script?

@jkreski You can try adding the following inside <head>.

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0">

to see if it helps. But, I was talking about doing it as an HTTP response header. Not sure how to do that for LiteSpeed that you're running, but you can search for info if the meta tags don't work.

@burnout426 I installed the Meta tags. They did not work after a Ctrl-F5. I chatted with my hostinger provider about the HTTP response header. They suggested a line of code to be put into my .httpaccess file. I did that but when I activated the file I couldn't get into my website because the file demanded a user ID and password and I didn't remember what I used so I re-deactivated it. They are still chatting with me but think it's the browser's cache that is the issue so I am not hopeful.

@jkreski Ctrl + F5 doesn't need those tags to work. It just works on its own. Goto the URL opera://settings/keyboardShortcuts and take a look at the "reload without the cache" command.

Not sure why it's not working for you.

They suggested a line of code to be put into my .httpaccess file.

It's usually .htaccess as mentioned at https://www.hostinger.com/tutorials/locate-and-create-htaccess, but understood about the password issue.

It might be something like this:

<IfModule mod_headers.c>
    Header set Cache-Control "no-cache, no-store, must-revalidate"
    Header set Pragma "no-cache"
    Header set Expires 0
</IfModule>

that you need to add to your .htaccess file (just while developing if you want). But, if you don't get things exactly right, pages on your site won't load.

But, you really shouldn't have to do any of this and ctrl + F5 should be enough.

However, see https://support.hostinger.com/en/articles/1583501-how-to-clear-cache.
