Cookie query.....?

Cookies are specific for each site or page. A later site cannot access the cookie information from a previous site. Each site adds their own cookie(s).

The purpose of the cookie is to make surfing a site faster and direct advertising of your interest. When you go back to the site you visited the cookie will tell the site "here is what this person did the last time they visited". The sites advertisers will then direct ads for you to see based on your previous visit. A new cookie is added that will tell them what you did on this vist.

Cookies, technically, are not harmful, although, they are considered as spyware. That doesn't change the fact that they are necessary. Even though they are necessary you do not need to keep most cookies.

Go to Tools>Internet Options>General tab>Delete Cookies button. This does not remove essential cookies needed for programs on your computer. This only removes the cookies from site and pages you visited.

You can add sites you trust to an allow list in Internet Options>Privacy tab>Sites button>add the URL of the site and click allow>OK>APPLY>OK. You can also block the cookies of sites here.

removing cookies will in no way affect your ability to access sites. Only if you DISABLE cookies in your browser will it affect your ability to access certain sites (usually those you need to log in, because your login information is stored in the cookie).

As far as performance goes, there is a minor hinderance in that the website has to reset a new cookie because u deleted your old one, but the difference is so minimal that I wouldn't really call it a hinderance. Certain sites allow you to store your customizations inside your cookie, and once you delete the cookie, then you have to re-customize, but that's as bad as it can go.

As a rule of thumb, I would say delete when not sure, it's not really going to affect much. Cookies have expiration dates anyway, so even if you don't delete them yourself, they will eventually be deleted unless you revisit the site in which case the cookie will probably be updated with a new expiration date.

Personaly I set my browser to erase any cookies when I exit the browser, like that if any personal info is stored in cookie, the next person who uses my computer can't open the cookie and read my info. (something u gotta watch out for on a public computer)

hope this helps
