What are cookies and cache?

I've heard every once in a while you want to remove your cookies and cache! Why is this? Is that true? And what are cookies and cache exactly? Like their purpose

The cache stores data from websites so you can load pages faster but on occasion the cache gets full and needs to be emptied.
Read here about cookies.
http://en.wikipedia.org/wiki/Internet_cookies
You can empty the Safari cache from the menu bar, Safari / Empty Cache.
If you have problems accessing a site, deleting the site related cookie can help. Go to Safari / Preferences then select the Security tab.
Click: Show cookies
You can delete all cookies or individually.

  • WHAT ARE COOKIES??

    CAN ANYBODY TELL ME WHAT ARE COOKIES AND HOW I CAN USE COOKIES IN MY PROGRAMMES??

    See http://www.cookiecentral.com/
    The FAQ section probably has enough information to get going.
    As for using them in an app... Google for cookies, sessions and servlets and I'm pretty sure there will be a document containing information on how sessions are implements using cookies (one of the main uses of cookies in webapps)

  • What is the diffrence between cookies and cache, is it safe to remove cache?

    what is the difference between cookies and cache , is it safe to remove cache ? . I had cleaned cookies many times but I have not removed cache , does it goes on increasing day by day ? please let me know

    Cookies are small files that contain information useful to a web site -- such as password, preferences, last date visited, etc. You may remove the cookies that you don't want adn since some of them are a privacy issue, many people remove them all.
    Cache is just a collection of data downloaded to help display a web page. After you leave a site, much of the cache is left on your computer and is no longer needed. You can always remove the cache because it will be replaced as needed.

  • What else can be done when certain websites say "Connection Reset" (cookies and cache already cleared)?

    All the websites use to load. For some reason over the weekend it only worked once. Did not update Moz. and did not add any new protection software. Cookies and cache cleared. Proxy changed to "no proxy". Firewall checked.....spywares deteected and deleted....i dont knwo what else to do.

    Did you also check the firewall?
    Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.

  • Cookie settings are correct;history,cookies and cache have been cleared.Still some sites say I need to enable cookies

    Cookie settings are correct;history,cookies and cache have been cleared.Still some sites say I need to enable cookies.

    You need to enable third-party cookies if you want to logout from Hotmail. If you do not want to enable third-party cookies (I don't) then you need to remove the live.login and passport.net cookies yourself.

  • I cannot access the internet, I tried to answer that said to go to settings, safari, tap clear history, cookies and cache, cut off, then on, but it did not work.  When I go to internet the screen is grey??? please help I am a new user!!

    I cannot access the internet the screen is grey, I have tried by using the answer from someone but it does not work...I went to settings, tap safari, then clear the history, cookies, and cache, then turn off ipad.  When I did that twice, it did not work.  How long does it take for the clear history to work?  I am a brand new
    user of the ipad2 and I am disappointed that this is happening already.

    Have you been able to access the internet previously and now it's suddenly not working, or are you still trying to access the internet for the first time on your iPad?  Are you at home trying to connect through your home router?  If you are at home, did you put your home routers encryption code as your password?  The encryption code is what your iPad is looking for and it is usually found on the router and is typically a 13 digit combination of letters and numbers.  Let us know......

  • Using Mac OSX 10.7.1: recently replaced our DSL modum & wireless router and suddently I can't get some web sites to load. Many do, but Twitter and others often do not. I've reset the browsing historty, forms, cookies and cache but it continues to happen.

    Ok, first thing, why are you doing anything with WAMP or XAMPP when you're running a Mac? MAMP should be what you want unless you're not explaining part of what you are trying to do.
    2nd thing, I haven't used MAMP in a while, but there are two possibilities for not seeing what you want to see once you have MAMP turned on. One possibility is that you already have "Web Sharing" turned on in your Sharing Preference Pane. If that is the case, port 80 will already be taken and you'll be seeing the default Apache install (files are stored at /Library/WebServer/Documents/). This would push MAMP to either not turn on it's web serving capabilities, or to push it to another port. The other possibility is that MAMP defaults to another port anyway. So instead of localhost, you might have to type in localhost:8080 or something similar. I believe the control panel that gets installed can take you to the currently MAMP-served page, and it can also help you change which port your serving on.
    80 is the default port for web serving and the ONLY port that will let you get straight to the server without having to type in webaddress.com:port# instead of just webaddress.com.

  • Firefox is running so slow even after clearing history, cookies, and cache

    My firefox browser suddenly started running very slow. I have cleared history, cookies, and cache. I have run scans, and even tried to uninstall and reinstall. it is still running slow

    flytnn,
    after a fresh install, Spotlight will need to reïndex the files on your internal disk — that happens each time a fresh installation takes place.
    I see that you have OS X 10.9.2 installed. Are you planning on installing the 10.9.3 update?
    Your installed version of Java is outdated — the most recent version can be downloaded from here.

  • What are cookie domains used for?

    there is a choice, can someone give me some suggestion?
    What are cookie domains used for?
    A/ to be easily recognizable by digital certificates that are also based on domains
    B/ to instruct the browser that the cookie should be send only to the domain it came from
    C/ to provide convenient way for the user to group cookies by their domains
    D/ All of Above
    E/ None of Above

    Not only does that not appear to be a Java question,
    but the OP didn't even take a guess at the answer and
    explain why he thought that that answer was correct.thanks! i support with your viewpoint, solve a problem will be the most important mission, but not consured! i am cognizant of this is a mistake to ask other questions in java forum ,but this question didn't far away j2ee project, though this is a choice, but only get a answer is not my original intention! i hope i can call on anyone join in this discussion!

  • Can someone help me when Firefox closes randomly it removes all the cookies and cache, and I am not able to restore lost tabs...?

    For a while now Firefox has randomly shut down for reasons unknown. Sometimes windows reports the error but not always. When I start Firefox back up again, it does not restore my tabs. Also as an added bonus it deletes the cookies and cache, and I don't know why. Furthermore this occurrence has become more and more frequent. Just in the last hour along before writing this complaint, Firefox crashed three times right as I switch users, but not every time I switched. I am a taboholic, addicted to tabs, sometimes 70+, and this is the final straw. This frequency became more and more prominent a few days ago. When it first crashed, Windows was kind enough to let me know of the error which first occurred one to two weeks ago. It has become the very bane of my internet surfing. Someone please help, or I will have to renounce my allegiance to Firefox and switch to the dark side that is Crome.

    <blockquote>... or I will have to renounce my allegiance to Firefox ...</blockquote>
    There is no citizenship oath involved in using Firefox, it's a piece of software.
    Look, if Firefox isn't generating any crash reports, you more than likely have an operating system or hardware issue. If Firefox is generating crash reports you can retrieve that information and post the report numbers here.

  • Cookies and cache files

    Hi all,
    I'm writing an AJAX / HTML app and on a local HTML page, I
    have to load remote content in an iframe.
    It seems that cookies set in the remote sanbox are persisted
    between application startups.
    Is there a way to clean those cookies on application shutdown
    or on next application startup ?
    Thanks for anwers !

    Hi all,
    I eventually found a way to solve this (for a Windows
    platform so far). Cookies and cache files are stored in the same
    folder as for Internet Explorer ("Temporary Internet Files"
    folder).
    I you want to delete cookies and cache, empty that folder
    manually or open the "Internet Options" popup in IE.

  • Firfox 8 is sometimes very slow to load random websites and others it loads quickly, IE8 loads all websites ok. Have cleared cookies and cache and allowed ff as exception in Windows firewall.

    I use FF 8.0 (x86en-US) as default browser, since update to 8.0 FF intermittently takes ages to load some websites, sometimes not loading the site at all. To rectify this I go back one page to the Google results or hyperlink and ask FF to load the webpage again. This usually solves the problem but not always. I have cleared cookies and cache and added FF to exceptions in windows firewall. The websites affected are not always the same and some that load quickly one day can take ages next time. IE8 loads all websites OK. Antivirus and malware scans all clear.

  • 0.41GB of my iPod Touh 4G' is taken up by something called 'Others'. What are 'Others' and can they be deleted or are they an essential part of the iPod and embedded in it? If not essential how do I go about deleting it to enable me to add other pictures

    0.41GB of my iPod Touch 4G's capacity is taken up by something callked 'Others'. What are 'Others' and will it be o.k to delete them? If so how do I go about doing it as there is no trace of a file on either iTunes or my iPod?

    Other content is typically miscellaneous data used by applications you have installed - could be save data (e.g. for games), or documents you've created. There's no easy way to determine precisely what it is, but the only way to clear it is to either delete it from within the respective application, or remove the associated application altogether - neither of which are typically practical.

  • What are ROWID and ROWNUM? Are they stored in database and where?

    Hi All,
    can anybody please answer this question
    What are ROWID and ROWNUM? Are they stored in database and where?
    Thanks,
    Srini

    ROWID can be thought of as a pointer to the physical location (on disk) of the (table) row.
    From a ROWID value, Oracle can extract the file, block-within-that-file and offset-of-the-row-within-that-block. Using these, Oracle can directly access a disk block to retrieve a row.
    ROWNUM is a just sequence number of a row within a result set of a query.
    As said by other repliers, both are not stored. They are 'constructed' when you reference them inside a query.
