A cookie often referred to as a web cookie, browser cookie, or internet cookie is a tiny piece of data sent from a website and collected in the device’s web browser while the user is browsing.

Every single the website is loaded by the user, the cookie is sent back to the server by the browser to notify the user’s previous activity.

Cookies were constructed to be a dependable mechanism for websites to remember useful information (like things added in the shopping basket in an online store) or to record the user’s browsing activity (which includes clicking specific buttons, logging in, or remembering which pages were visited in the past.

Cookies can also remember passwords and form content a person has formally entered like a credit card details or an address. How to clear iPhone with cookies is already mentioned.

There are other kinds of cookies that perform important functions of the modern web. Perhaps, the most important of all ‘authentication cookies’ is the most usual system used by web servers to find out whether the user is logged in or not and the account with which they are logged in with.

Without such an operation, the site would not identify whether to send a page having delicate information or require the person to recognize themselves by logging in.

The protection of an authentication cookie usually depends on the security of the issuing website and the person’s web browser, and on whether the cookie data is converted into code (encrypted).

Protection threats may allow a cookie’s information to be read by a hacker, utilizing to gain access to user data, or utilized to gain access (with the user’s certifications) to the website to which the cookie belongs.

At the beginning of the article, how to delete cookies on iPhone is informed.

There are certain drawbacks of cookies besides the privacy concern. They do not always particularly identify users, they are utilized for security attacks and they are usually at odds with REST (Representational State Transfer) software architectural style.

How to clear space on iPhone is detailed in the article. So, clear caches and cookies on your device with these steps.

Inaccurate identifications take place. If on a computer, more than one browser is used, each of them often has a separate storage location for cookies.

Hence, cookies do not recognize a user, but the association of a user account, a computer, and a web browser. Hence, any person who uses more than one accounts, browsers, or computers has multiple sets of cookies.

Similarly, cookies do not isolate multiple users who share the same user account, browser, and computer.

The usage of cookies may produce an inconsistency between the state of the client and the position as stored in the cookie. If a person acquires a cookie and then selects the ‘Back’ button on the browser, the position on the browser is usually not the same as before that acquisition.

For example, if the shopping basket of an online shopping constructed using cookies, the content of the basket may not change when the person goes back to the browser history.

If the person selects to press a button to add an item in the shopping basket and then selects the ‘Back’ button, the item remains in the shopping basket. Though, this might not be the intention of the person, who perhaps wanted to undo the addition of the item.

This may lead to confusion, unreliability, and bugs. Therefore, web developers should be aware of this particular issue and must take measures to control such situations.

There are other mechanisms that operate the same as that of cookies. They are IP address, URL (query string), hidden from the fields,, HTTP authentication, an identifier for advertisers, ETag, Web Storage, Cache, and Browser fingerprint.

Based on the IP address of the computers, some users may be tracked requesting the page. The server is aware of the IP address of the computer operating the browser or the proxy (if any is used) and could link a user’s session to the IP address theoretically.

Generally, an IP address is not a reliable way to identify a user or track a session. Most of the computers constructed to be used by a single user, like an office or home PCs are behind a NAT (Network Address Translator).

A more accurate method is based on embedding data into URLs. If the cookies are not enabled, the Java Servlet and PHP session mechanisms use this method.

This method involves a web server appending query strings to the links of a web page it is responsible for while sending it to a browser. When the person follows a link, the browser gives back the attached query string to the server.

Query strings utilized in this way are very much similar to the cookies, both of them being arbitrary pieces of knowledge chosen by the browser and returned by the browser.

But there are some differences. The query string is a part of the URL, if the URL is reused later, then the similar piece of detail is sent to the server.

Upon that, even if the same person uses the same page twice, there is no assurance that the exact same query string will be used in both views.

For instance, if the same person visits the same page but coming from the internal of a page to the site for the first time and for the external search engine for the second time, the query strings are different but the cookies will remain the same.

The drawback of the query string is security. By following the above steps, you can clear cookies on iPhone.
