Mapping this knowledge onto your questions, the following should apply:

• Cookie with Domain=.example.com will be available for www.example.com
• Cookie with Domain=.example.com will be available for example.com
• Cookie with Domain=example.com will be converted to .example.com and thus will also be available for www.example.com
• Cookie with Domain=example.com will not be available for anotherexample.com
• www.example.com will be able to set cookie for example.com
• www.example.com will not be able to set cookie for www2.example.com
• www.example.com will not be able to set cookie for .com

And to set and read a cookie for/by www.example.com and example.com, set it for .www.example.com and .example.com respectively. But the first (.www.example.com) will only be accessible for other domains below that domain (e.g. foo.www.example.com or bar.www.example.com) where .example.com can also be accessed by any other domain below example.com (e.g.foo.example.com or bar.example.com).

The ParseChildrenAttribute class allows you to specify parsing logic for a custom server control by marking the server control with the ParseChildrenAttribute metadata attribute.

Marking your server control with the metadata attribute ParseChildren(true) instructs the parser to interpret the elements that are contained within the server control's tags as properties. In this scenario, the ChildrenAsProperties property is true.

Marking your server control with the metadata attribute ParseChildren(true,"<Default Property>") sets the DefaultProperty property to the name of the property that is passed into the attribute.

Marking your server control with the metadata attribute ParseChildren(false), the default value, instructs the parser to interpret the elements that are contained within the server control's tags as content that will be parsed with an associated ControlBuilder that is, as controls. In this scenario, the ChildrenAsProperties property is false.

The PersistChildrenAttribute is used in combination with the ParseChildrenAttribute to determine how nested content of a control is interpreted. If PersistChildrenAttribute is true and ParseChildrenAttribute is false, the nested content contained within an ASP.NET server control is persisted as controls. If PersistChildrenAttribute is false and ParseChildrenAttribute is true, the nested content is persisted as properties of the server control.
