SimpleUpdate Release status: unknown
Implementation	Page action
Description	This extension allows updating page with just one URL hit.
Author(s)	Amir Szekely
Download	see below

The SimpleUpdate extension allows updating pages with just one URL hit. It's ideal for automation scripts, such as software release scripts. It requires an extension on the server side, but it makes the client usage much simpler than existing solutions as it has no external library requirements.

To prevent abuse and vandalism, only sysops are allowed to update pages.

WARNING: always pass the password using POST and not GET method!
