Because of the utilization of HTTP pipelining, Ubuntu APT had problems working with web proxies like Squid . The problem was fully documented in this bug report: disable apt http pipelining in quantal which also provided a way to turn off pipelining manually: apt-get -o Acquire::http::Pipeline-Depth="0" -y up... Pipelining is turned off by default as of apt (0.9.6ubuntu1) - Ubuntu Linux 12.10 'Quantal Quetzal' - see link above.

Link to official Java networking properties page: http://docs.oracle.com/javase/7/docs/technotes/guides/net/properties.html http.keepAlive (default: true) Indicates if keep alive (persistent) connections should be supported. Persistent connections improve performance by allowing the underlying socket connection be reused for multiple http requests. The default is true and thus persistent connections will be used with http 1.1 servers. Set to 'false' to disable the use of persistent connections. http.maxConnections (default: 5) If HTTP keep-alive is enabled, this value is the number of idle connections that will be simultaneously kept alive, per-destination.

IE categorizes web sites into different security zones . You can put specific sites into a certain zone with the "Security" tab in the "Internet Options" dialog. If a site is not specifically configured, IE has default algorithm to assign it to a zone. which can have unexpected results. For example: http://myserver is in the Intranet zone because the name does not contain a dot (.). But if you are using the IP address of myserver , then it goes to the Internet zone, even though myserver may have an internal IP address, or even on the same subnet: http://192.168.2.1 . IE8 and before displays the Zone of a web site in the status bar. IE9 removed the Zone info from the status bar. You...

The landing page after login can be configured with the default-target-url attribute of form-login . If a user was redirected to the login form after requesting a restricted URL, she's redirected to the original requested page after successful login. An easy configuration looks like this: <beans:beans xmlns="http://www.springframework.org... But there are times that you want to do more initialization after login (such as loading user data), or apply more complex logic before redirecting. This is where the authentication-success-handler-ref attribute comes into play. You create a class that implements org.springframework.security.web.authentication.AuthenticationSuccessHandler and use that as the authentication-success-handler-ref : <http entry-point-ref="authProcessFilterEn... This is a skeleton implementation: public class MyAuthenticationSuccessHandler implem...

The annotation @org.hibernate.annotations.Type overrides the default hibernate mapping type used for a column. This can usually be omitted since Hibernate normaly infers the correct type to use. But @Type is required in ambiguous scenarios such as a java.util.Date attribute, which can map to SQL DATE , TIME or TIMESTAMP . You use the @Type("timestamp") annotation to tell Hibernate that a timestamp converter should be used, which identifies an instance of org.hibernate.type.TimestampType . @Type can also be used to identify custom type converters, which can be defined with @TypeDef at the class level: @TypeDefs( { @TypeDef( na... or with an xml file: <?xml version="1.0"?> <!DOCTYPE hibernate-mappi...

This is a simple Hello World application with Spring 3 MVC. Like the default Apache HTTPd welcome page, it displays " It works! " when successfully deployed. The sole purpose is to show the minimum elements needed to setup Spring 3 MVC. I use Maven since it's so much easier than downloading the dependencies manually.
