Website not updating automatically on all PCs
Posted: Thu Dec 13, 2012 7:00 pm
I'm having a weird problem. Our domain is http://www.lakeviewschools.net. When you go to the website, there's a slideshow. For the longest time (years), there wasn't a slideshow in that spot, but the 4 buildings in a 2x2 tile. I changed it to a slideshow a few months back. Right when I switched it, I just took those same 4 buildings that were in a 2x2 spot there and had the 4 buildings rotating in the slideshow until I could find some pictures.
When I had it as 4 buildings, the resolution was really low, so I made the slideshow picture about half the size on the website. With the new pictures, they were really high resolution. I scaled them down to be acceptable size for a website but still was able to be larger on the website.
We have lakeviewschools.net as the homepage for most PCs at the school. For some reason, most of the PCs are showing the larger area that the new pictures are scaled to, but still showing the same 4 old pictures in the upper left corner of the box.
I can fix it one PC at a time by clicking the compatibility button on and off and it seems to force the browser to go out to the Internet and realize the website has changed.
Why is this happening? I don't know if what a browser does is just look at the headers and checks some kind of check bit or something to see if the website appears to have changed, and if it hasn't, to just load from local cache. Is there coding I need to put in the website to tell the browsers to always look for changes and not load the website from cache?
