Hardware peripheral supplier for the Atari ST

Over the years there’s been a few different people who have designed and built custom peripherals for the Atari ST, like SD Card readers and Ethernet adapters. These were usually sold as one-off custom orders, and built on demand. It looks like there’s a company called Lotherek that’s started to manufacturer many of these with permission from the original developers – check out their site here.

Fiddler – monitor HTTP requests from your browser

Fiddler is invaluable for monitoring HTTP requests from your browser. If you’re investigating HTTP header usage and the effort on caching static content, Fiddler is definitely the way to go, since using the Developer Tools in IE, Chrome or FireBug in Firefox don’t always give you an accurate picture of the actual outgoing HTTP requests. IE is the worst… its developer tool shows HTTP requests going out even though the files are being retrieved from cache. If you really want to see what’s going on then you need something like Fiddler.

To review requests against a server running locally (against localhost), there’s a number of tips in the docs here, but the simplest approach seems to be to use your own IP address (actual address, not 127.0.0.1) instead of localhost or any of the other approaches listed on this page. It works without any other changes.
