thanks for the reply,
But if I prevent the caching the bandwidth consumption of my page will increase dramitacally and the pictures will have to load again and that will take time. I'm using php and mysql database and I just want to ensure that the I get the correct data for the database.
I've done some reviews on the sources of some page, on of them is this forum and I did not see any cach control tags in the header or anywhere else!!!! and I get the most recent pages from it. How did they do it?????
thanks
