An idea to withstand Digg effect

[dollars5]

Hi,

recently some of our client's sites were stormed by digg effect. I just struck with this idea - pls provide me directions that I can proceed on to getting a Digg resistant Pligg installations (to an extent - bandwidth outages cannot be solved - pls not in that direction )

The plan is this:
From Admin panel: Select a story that you see advancing to front page - generate HTML page (static content) of it, generate htaccess code to redirect the requested page to this new static page. The admin will then copy that static content and paste it into the htaccess - done.

Reason:
- Many sites (esp ones on shared hosts) die due to inadequate CPU share and memory
- most diggers will just come to see the content and they donot interact with the site anymore after initial viewing (if you have other links -they will just take that path) - all they know is to follow links.


Disadvantages:
- the comments will temporarily be disabled but can be allowed if user logged in - no redirection (dunno how difficult that will be)
- does not save bandwidth.


please suggest me some ideas or points to get started I will get a module on it sooner.

Regards.

Why not just re-direct to something like coral cache, like this wordpress plugin does:

If a referral comes from a high traffic site like digg, it sends it to the cached version instead. You could do it on site, or re-direct to a pre-existing cache off site. Maybe even only activate the re-direct once a certain number of hits per minute are registered, or something of that nature.

There are disadvantages in redirecting to corel cache - esp if you monetize site with CPM advertisements

Yes, and there are disadvantages to every method in this situation.

If you are going to create a flexible module, it should really give the admin the choice. Either create a static html page on site, or re-direct to a pre-existing cache. Many shared servers *may* prefer the latter option. Just my 2 cents.

Stumbled upon this script just now. A generic script that redirects to Coral Cache. Figured it would help if anyone is still interested in this useful script.

To use this code, simply include it above all the PHP code in your website. You must make sure there is no output (including whitespace) otherwise the script will fail when it comes to redirection.
