The Goal
You want to drop your site down, take it off-line, for maintenance, upgrades, because you have a security concern - whatever.
Discussion
The two broad types of approach are:
o Provide a web tool to give admins the ability to bring a site up or down
o Rely on command line (eg. ssh) access to the web server
The pros of the former is that any idiot can do it. The downside, of course, is that any idiot can do it.
The pros of the latter is that it’s a simple and immediately effective change, and requires no PHP coding.
The approaches
o Jedd’s take - using CLI and a file/name swap,
o Rogierb’s take - using a pre-system hook
o Natebot’s take - using .htaccess
o {Your CI login-name goes here} take? - description of your approach goes here ...
Note to would-be contributors - it’d be just fantastic if you’d spend the time sharing your approaches with the world, but please resist the temptation to provide a link to another site. First, sites come and go, and dead links are a real pain in the proverbial. Second, off-site material doesn’t get discovered by searches within the wiki. Third, the world has enough web pages that are ‘lists of links’ - we don’t need to add to the collection. And finally - the whole idea of this collection of Approaches is so that users can see what you do - so can you please put your name on anything you contribute, so people can PM you if they want to clarify something?
Need to automatically insert category/subcategory listing here somehow, later - for the moment I’ll handcode in the first couple of links
