Recently I had a weird problem while using Tomcat - sessions would get lost when using Microsoft's Internet Explorer.
Since Tomcat stores the session id as JSESSIONID cookie, the session would get lost when the cookie is not stored.
Same behavior occurs with other web servers including IIS and Resin.

After further research, it seems that IE does not store cookies at default privacy settings unless a P3P policy is
provided for the site. In order to bypass this problem, a basic P3P policy needs to defined and included in the site.
I used IBM's P3P editor to generate a basic P3P XML policy file and the following snippet of HTML code to enable it.

This is still true as of 2011: [http://blog.toppingdesign.com/2011/11/18/ie-iframe-p3p-cookies-oh-my/]

 * One of the recent problem that I ran across at work is an easy way to do highlighting for form fields.
 * Of course the best way would be CSS 2
 * (as shown here [http://www.cssdrive.com/index.php/examples/exampleitem/focus_pseudo_class/]) but alas,
 * IE does not support that.
 *
 * The alternative is JavaScript onFocus and onBlur method. However, one thing which I also wanted to avoid
 * is changing over 200 different pages in our system to add those in. So instead, I wrote a simple piece of
 * Javascript which attaches the event handlers on the fly. The best part about this is that the actual form
 * does not need to be changed - just include the Javascript on the bottom of your webpage. The code is as follows

* One of the questions that recently came up is how to remove vowels from Hebrew characters in Unicode
* (or any other similar language). A quick look at Hebrew Unicode chart shows that the vowels are all
* located between 0x0591 (1425) and 0x05C7 (1479). With this and Javascript's charCodeAt function, it
* is trivial to strip them out with Javascript as follows
