Questions tagged [postback]

A postback is a technique in web development in which a page sends an HTTP POST back to the same form on the server.

The term postback has two meanings depending on the context, one in relation to web development, and one in relation to open-source software.

In the context of web development, a postback is a page sending an HTTP POST back to the same form on the server.

In the context of open source software, the term "postback" is often used to describe making your changes available in source code form. Questions that would use this meaning of the tag are generally off-topic on Stack Overflow.
