You don't really need POST, unless you're going to be uploading largish forms full of text. GET with a URL of http://192.168.0.30/foo?a=b&c=d&e=f are eminently usable. If your HTML doesn't specify POST, the web client will format the form values into a=b, c=d, and e=f as needed. On the EW2 end you'll have to undo the encoding, but no biggie. IMHO, the example web server for the EW2 is a piece of crap. Once I figure out how to upload code (compilation is working fine), I'm going to start working on a vastly improved version. Wishlist: o configurable assignment of buttons to functions. o sensing of the four opto-isolated inputs. o control of the two relays o control of the beeper o control of the status light. o ability to send stuff to the LCD. o 1-Wire code, so you can read a temperature ibutton from the web. o telnet server for the serial port. The idea is to make it useful out of the box, without *needing* to do any development. Also, the EW2 really, really really needs a BOOTP client. DHCP would be better, but BOOTP at a minimum. It also needs to use a locally-assigned Ethernet address (02:03:04:05:06) rather than a multicast address (01:02:03:04:05). It would be much better if the Olimex folks had bought an OUI, but I guess they haven't. -- --My blog is at angry-economist.russnelson.com | I'm giving a short Crynwr sells support for free software | PGPok | talk at WTF, Isen's 521 Pleasant Valley Rd. | +1 315 268 1925 voice | stupid net conference: Potsdam, NY 13676-3213 | FWD# 404529 via VOIP | http://stupidnet.com
