How can restrict images for not storing in browser
Or in another way how can we delete browser cache files
I have tried header in php. Also i tried Cache-Control
of meta tags, but still images are cached and even it
update image, browser is showing old image only.
I need to generate image dynamically on key press event
of text. So based on the text entered, image is to
drawn and shown. I have successfully generated image
but browser is always showing old one. I need something
that can be managed through code.
I tried to append a random number each time image is
retrieved. But by doing so, image is cached in bulk
with random numbers.
Any suggesstions will be helpful.
Thanks in advance.
