History.js gracefully supports the HTML5 History/State APIs (pushState, replaceState, onPopState) in all browsers. For HTML4 browsers it will revert back to using the old onhashchange functionality. All major browsers are supported.
This is a simple test page to get started:
<html>
<head>
<title>Test History</title>
...
Note: state url must be provided for IE to generate a unique hash. YOu can prefix the state url with '?' ('#' does not work).

This is a simple example to demonstrate the templating power of JSF facelets. If you've used struts tiles before, you'll recognize the simplicity of templating with facelets. I've stripped out everything else except the pages themselves, just to put our focus on facelets. This is a Maven based project, and you need Tomcat (or any servlet container) to run the resulting webapp. To begin with this is the list of files:
./pom.xml ./src/main/webapp/home.xhtml ./src... I left faces-config.xml in there for completeness sake, it may not be needed. The Maven POM ( pom.xml ): <?xml version="1.0" encoding="UTF-8"?> <project... Web app configuration ( WEB-INF/web.xml ): <?xml version="1.0" encoding="UTF-8"?> <web-app...

jQuery automatically maps HTML5 custom data attributes to data storage associated with the data() method. Here's an example:

Three key concepts are associated with internationalization (I18N): Locale: a locale is identified by a language code along with an optional country code. For example: en for English, en_US for US English, zh_CN for simplified Chinese. Resource Bundle: a resource bundle is a properties file localized for a specific locale. For example, messages_en.properties may be a resource bundle for English, messages_zh.properties may be a resource bundle for Chinese. Basename: a basename identifies the same set of messages represented by all related resource bundles. In the above example, the basename is messages . When a user request comes to a web application, the resource bundle is retrieved using the basename and the preferred locales . The preferred locale can be either application-based or browser-based . When...

cURL is a command line tool for transferring files with URL syntax. The main purpose and use for cURL is to automate unattended file transfers or sequences of operations.
It's really easy to see HTTP headers with curl:
C:\>curl --head http://www.google.com
HTTP/1.0 ...
or, headers and page together (dump headers to stdout):
$ curl --dump-header - http://www.google.com HTTP/...
Download openssl from openssl.org:
curl http://www.openssl.org/source/openssl-0.9.6m....
C:\>curl --help

<!-- Without body content, used to export vari... In my opinion, the version without body content is pretty much useless (the <c:set> tag is a lot more meaningful for this purpose). If body content exists, it is inserted into the page if the testCondition is true . Optional attributes var and scope may be specified. If var is specified, a variable whose name is the value of var is exported to the associated scope ( pageScope if no scope is specified). The type of the exported variable is Boolean and its value is the value of the testCondition . <c:choose>, <c:when>, <c:otherwise> These tags imitate the Java control structure if...else...
