Is there a way to delete only cookies in safari 5.1?

Is there a way to delete only cookies in safari 5.1?
If you go to Preferences -> Privacy -> details, you can choose to remove "website data" but sometimes this includes the local cache and also local storage.
Is there any way to delete JUST/SOLEY the cookies that the browser stores?

Go to ~/Library/Cookies.
Move the Cookies.plist to the Trash.
~ (Tilde) character represents the Home folder.
For LIon: To find the Home folder in OS X Lion, open the Finder, hold the Option key, and choose Go > Library

I have tried several ways to delete the cookies listed in options and nothing works to get rid of them.

I have tried all of the methods to delete the cookies that are suggested on your support site. I have tried them if the selection in Options is for cookies allowed and with cookies not allowed. Also with 3rd party cookies allowed and not allowed. Normally, I have it set at cookies allowed but 3rd party cookies not allowed.
I have tried CCleaner, Euslings Cleaner, Auglogics Cleaner, Wise Cleaner, SuperAntiSpyware, Spybot, and WinPatrol, plus deleting the temp files in Windows. All that software cleans out cookies. I also have Spyblaster set to protect against hundreds of tracking cookies. It was SuperAntiSpyware that brought the problem to my attention in the first place. It just started doing it approximately a few weeks ago but only the passed several days have I been working hard to get those cookies deleted. There must be a couple hundred of them. I did manage to delete about 5 or 6 of them but the others won't budge. I want to clean them all at and start from scratch and monitor them on a daily basis. I don't want most of them. SuperAntiSpyware claims it deletes them but when I go to Options in the browser they are still there. SuperAntiSpyware claims the cookies are there every time I run the program before shutting down the computer.
I just added that Troubleshooter and looked at information. I'm sorry but I'm not understanding anything. I'm not that computer savvy.

You may have installed an extension that adds so called opt-out cookies to Firefox. 
Such opt-out cookies are send instead of the normal cookies and you can't remove such opt-out cookies unless you disable or uninstall the extension.
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.

Some websites are saying I need to enable cookies when it is enabled already. I already tried deleting the cookie, deleting all cookies, clearing my cache, and uninstalling and reinstalling Firefox. How do I fix this?

I am trying to access my school's library database. When I log in to access the library, it tells me that the site needs to verify me by sending me a cookie. There's a link to log in again, but when I click it, it says "404 not found". My privacy settings already have cookies enabled, and I tried deleting the cookie and revisiting the site but the same thing happens. I also tried uninstalling Firefox and reinstalling it, but that didn't work either. I am able to access the library on my iPod Touch, and I've tried other browsers on this compute and I can't access them on other browsers either. So it is clearly some issue with my computer that is preventing me from accessing this library. I don't know how else I can resolve this issue and I need to do so ASAP because my inability to access the library off campus is severely hampering my ability to get my work done.

I have a MacBook Pro 13" and am using Airport Time Capsule and iCloud. I delete my cookies all the time, but every so often the cookies reappear after rebooting. It is the exact same amount of cookies each time, so I wonder why they're being reloaded?

I have a MacBook Pro 13" (2010) running OS X 10.9.2 and have Airport Time Capsule. I routinely delete my cookies and often (every couple days or so) when I reboot, a number of cookies reappear in my Safari settings. The number of cookies that reappear is exactly the same when it does it (351 cookies) so I'm wondering if it is related to my Airport Time Capsule or possibly iCloud? How do the cookies get back into my MacBook Pro? Or.... Have they ever actually left? Befoer I reboot, I delete them and sometimes they stay gone for 24hrs or more, but then reappear the next time I reboot. Can someone tell me if there is a way to clear the cookies so they won't come back?

Blocking all cookies in Safari does not work. Deleted cookies will not stay deleted. There are numerous threads on this going back years, both in these forums and elsewhere. Many claim to have submitted the issue to Apple, but I have never seen anyone post a reply.
I have seen many suggested fixes that involve finding the cookies file, some including Terminal manipulations, and none seems to work universally. I can find noplace where Apple addresses this officially with an actual Apple-approved explanation or how-to.
Bottom line, your browser's security features should do what they claim: delete cookies. When they come back without ever even visiting another page, this is clearly not working in the way a reasonable user would expect.
Bottom line, Safari does not protect users' privacy in the way it pretends to and, after so many years of this issue, it appears that Apple wants it this way.
Having spent way too much time on this, I realize the choice is between Safari which is pretty well optimized; Firefox which is a lot pokier, at least for me; and Chrome, which I assume funnels personal information directly to Google.

I think I updated to a newer version of firefox, I can no longer get into my gmail account . I can get onto google however. I deleted all cookies also. What have I done wrong? I didn't have this problem before.

I can no longer get into my e-mail account on Google. I tried to update my version of Firefox. I also deleted all cookies in Google. When I click on Firefox, it opens to my Google home page. Then when I click on "gmail" it keeps repeating "redirecting" and does no more. What did I do wrong or forget? Help!

I deleted my cookies and now i can't access gmail facebook and other sites

i deleted my cookies and now i can't access gmail facebook and other sites

Thanks, but I tried that and was directed to set up a new password which I did. But, it still wouldn't let me go to my existing Gmail. I was asked to set up Gmail account. I also tried accessing my Gmail from Yahoo. Failed. Someone suggested setting up another Gmail address so that when you logged on it would ask you which Gmail to open. This didn't work and only made the problem worse. Google Help is no help. I guess the only way to access Gmail is with my iPad, but it just isn't right!

How to use cookies in jsp

Hi all,
I'm new to jsp, please let me know how to use cookies with jsp.
I have three web applications, in run time I have to switch from one application to another application based on single login page. I have taught cookies are one of the solution. But while I'm googling I unable to get such a good material.
please give some examples,
Thanks in advance.

Read a cookie in jsp
HttpSession session = request.getSession();
Cookie cookie_session = getCookie(request, "COOKIENAME");
 if (cookie_session == null) {
 sesID = session.getId();
 } else {
 sesID = cookie_session.getValue();
 }or
get all cookie in the browser
This gets all the cookies and according to the cookie name given u can get the cookie value
Cookie[] cookies = request.getCookies();
 if (cookies != null) {
 for (int i = 0; i < cookies.length; i++) {
 if (cookies.getName().equals(cookieName))
 return cookies[i];
 }but i am not sure if this works for ur requirement try and see

Sending Cookie to JSP Through Servlet

I am trying to read a cookie through JSP and cookie is defined in Servlet.
Here is what happening?
First JSP, user click on a hyperlink to select a category and that invokes servlet. Servlet has to pass selected category to another JSP page through a cookie.
Here is the code for Servlet
Cookie c1 = new Cookie("selectedCatgId", catgId);
response.addCookie(c1);
Target is a JSP, which I am calling through
RequestDispatcher dispatcher;
dispatcher = request.getRequestDispatcher("target.jsp");
In target.jsp, when I am reading the Cookie
Cookie cookies[] = request.getCookies();
Cookie currCookie;
if (cookies != null) {
for (int i=0; i<cookies.length; i++) {
currCookie = cookies;
if (currCookie.getName().equals("selectedCatgId")) {
parentCatgId = currCookie.getValue();
This shows me one previous value of the cookie, not the current value I passed through the servlet. Not what I set in servlet.
Can anybody help in this? I am not sure where I am wrong?
Thanks, Vikas

You are passing information on the server side. So, you should use attributes and not cookies.
Also, take a look:
Cookie c1 = new Cookie("selectedCatgId", catgId);
response.addCookie(c1); //here you added a new cookie that has not been sent to the client yet
RequestDispatcher dispatcher;
dispatcher = request.getRequestDispatcher("target.jsp"); //Here you called a new JSP page. A server side operation.
Cookie cookies[] = request.getCookies(); //Here you are reading a cookie sent by the client. But the c1 has not been sent to the client yet. So you didnt get this cookie on the request.

I want to delete all cookies when I close Firefox except for one website. Is this possible?

I have a website bookmarked that I use frequently and I have set my preferences on the site. I have Firefox set to allow cookies from this site. Is there any provision to delete all cookies except this site when i close Firefox?

There is a plugin for that, search "cookie" on the plugins site and you'll find it.

Setting the cookies in jsp

Hi
Iam trying to add the cookie into local machine.Problems is i written cookie program in cookietest.jsp then i incude this jsp into index.jsp.When iam accessing the index.jsp cookies are not setting But when iam acessing cookietest.jsp cookies are adding.why index.jsp accessing time not adding??please help me how to achive this one.
below the code snippet
**********************cookietest.jsp***********************
<%@ page import="java.util.Date"%>
<%@ page import="java.net.*"%>
<%
 Date now = new Date();
 String timestamp = now.toString();

</HEAD>
<BODY>
</BODY>
</HTML>
**************************end*****************************
***********************index.jsp***************************
<jsp:include page="/cookietest.jsp"/>
Thanks for advace
Venkatesearlu Ravi

Actually this is requirment
I have to add the that cookie code snippet to every
page.SO what i did is i placed the cookie code
snippet into footer.jsp.This footer jsp will include
every page..Here cookie is not adding.
Is there any solution.I also tried this with JSTL c:import, since the JSTL1.1 spec says that c:import covers many of the shortcomings of jsp:include.
/p/cookies/include.jsp
<%@ page import="java.util.Date"%>
<%@ page import="java.net.*"%>
<%
Date now = new Date();
String timestamp = now.toString();
Cookie cookie = new Cookie ("Venkateswarlu", "ravi");
cookie.setMaxAge(365 * 24 * 60 * 60);
response.addCookie(cookie);
%>
/p/cookies/page1.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:import url="/p/cookies/include.jsp"/>
<html>
<head><title>Page 1</title></head>
<body>
<%request.getCookies();%>
</body>
</html>
/p/cookies/page2.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:import url="/p/cookies/include.jsp"/>
<html>
<head><title>Page 2</title></head>
<body>
<%request.getCookies();%>
</body>
</html>
But the result is the same as jsp:include as far as setting HTTP Headers (Cookies) is concerned.
So the conclusion is that you can't really set HTTP headers in include files.
Then, you can try it with Servlets instead of JSPs. But then, you'll need to call the servlet each time, before every JSP is invoked.
I don' know how that's done. Probably through Filters
(a wild guess)

Firefox doesn't delete my cookies when I clear all history.

When I go to options and clear all history (everything, all boxes checked), firefox does not delete my cookies because I am still logged into accounts. Not too sure about deleting all my history and cache either.
Is there a setting I am missing that bypasses certain accounts from getting deleted?

Is this about "Clear history when Firefox closes" to clear the cookies when you close Firefox?
If you leave tabs open when you exit Firefox then Firefox stores the cookies in sessionstore.js as part of the session data.
You can set the browser.sessionstore.privacy_level pref to 2 (never) or 1 (non-HTTPS) on the about:config page to disable saving cookies via session restore.
You can open the about:config page via the location bar

Weather page stuck on initial date from the first time I opened it. Will not update. Have deleted history, cookies. Comics do not update either, still stuck on the original day I opened them after installing Firefox. Help Please

Have updated all plug-ins and add-on. Not sure if this is related or not, when I tried to use "live chat" that link would not work.

If you are using bookmarks to open the sites then make sure that you do not use bookmarks that have GET data appended (?xxx=xxx) to specify a specific page.
* "Clear the Cache": Firefox > Preferences > Advanced > Network > Offline Storage (Cache): "Clear Now"
* "Remove the Cookies" from sites causing problems: Firefox > Preferences > Privacy > Cookies: "Show Cookies"
If clearing the cookies doesn't help then it is possible that the file cookies.sqlite that stores the cookies is corrupted.
Rename (or delete) cookies.sqlitecookies.sqlite-journal and cookies.txt, if they exist, in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] in case cookies.sqlite got corrupted.

The wording on the delete/edit cookies menu is NOT GOOD...

When I want to delete INDIVIDUAL cookies it is too easy to accidentally delete ALL cookies.
Here's what should be changed...
1) REWORD the button to the left. It now says, "Remove Cookies." It SHOULD say, "Remove SELECTED Cookie(S)."
2) There should be a WARNING box, if one hits "Remove All Cookies" by accident. Another box should pop up that says, "Are you sure you want to remove ALL cookies? (this cannot be undone)"
I hope FF reads this.
(note: Yup -- I just deleted all cookies by accident)

I use code in userChrome.css to remove all the Remove buttons and use the Delete key to remove (selected) items.
Add code to the userChrome.css file below the default @namespace line.

The customization files userChrome.css (interface) and userContent.css (websites) are located in the chrome folder in the user profile folder.
