The HTTP You Don’t Know

After working with the ATOM Publishing Protocol (APP) and paging through the HTTP RFC, it is clear that the full potential of HTTP has not been explored. APP uses request methods of PUT, and DELETE which are rare to see in use right now. But, I came across the if-* header fields a while ago that seem to offer some exciting potential too. Here’s a couple…

If-Match

A client that has one or more entities previously obtained from the resource
<br />
can verify that one of those entities is current by including a list of<br/><br />
their associated entity tags in the If-Match header field.<br/><br />
<br/><br />

If-Modified_since

The If-Modified-Since request-header field is used with a method to
<br />
make it conditional: if the requested variant has not been modified<br/><br />
since the time specified in this field, an entity will not be<br/><br />
returned from the server; instead, a 304 (not modified) response will<br/><br />
be returned without any message-body<strong>.<br/><br />
<br/><br />
</strong>

These headers look like they conflict with OpenSearch in some way. They both have slightly different characteristics. I’m not sure where I stand on this.

The Read/Write Internet

Internet application development needs a paradigm shift. The problem to me is that everything to date has been geared toward the READ based Internet. The READ/WRITE Internet will usher in new paradigms, new tools, and a new era. I don’t believe we are there yet, despite what some people would have you think.

I’m signed up with a trading company called CMC. They provide a market for CFD’s, FOREX, plus some other stuff. Every now and then I will get email from them for courses, promo’s, news. I found myself laughing out loud at their last course promo mail out. It’s the same crap, but in a different wrapping. Here’s some excerpts:

See how people have made over 100% in 3 months trading CFDs sensibly with defined strategies that you can learn.

• Don’t believe anything anyone tells you; ask for account statements as proof of results you are shown (HomeTrader can provide them).
• Vague ideas with no clarity are not repeatable; you have to have exact strategies that leave nothing to chance.
• You need to treat trading seriously; if you dabble around the edges and don’t know what you’re doing, you will lose your money.
• Trading is a great way to make money; to earn extra income or to grow your capital base.

Neil Ridley

I don’t know Neil, but he’s got the sort of name I can trust. Holy crap, what have I been wasting all these months coding for? All I need is $149 and a free day! Just leave your luck at the door folks, it’s not needed here.

Don’t forget everyone, with great power comes great responsibility. Use these secrets with care.
