In the life cycle of a page, the current state of the page is hashed to a string and is saved into a hidden field. When opening a page with the View Source operation you...

If we don’t take care about how we feed our ASP .net pages… we will find that they will tend rapidly to gain too much weight, this can provide us a lot of headaches. Let's see how to reduce the size of our pages.
