It used to be that when you registered a media type, a URI scheme, a HTTP header or another protocol element on the Internet, it was an opaque string that was a unique identifier, nothing more. Sure, there are some...

Last week found lots of HTTP-ish folks in Prague for IETF 80. In short, the good bits: HTTPbis HTTPbis had a cracker of a meeting, with three RFC2616 authors and representatives of all five major browsers in the room....

The IESG has received a request from the Hypertext Transfer Protocol Bis WG (httpbis) to consider the following document: 'Use of the Content-Disposition Header Field in the Hypertext Transfer Protocol (HTTP)' <draft-ietf-httpbis-content-disp-06.txt> as a Proposed Standard The IESG plans...

I’m going to try to start blogging more updates (kick me if I don’t!) about what’s happening in the world of HTTP. HTTPbis The effort to revise the core HTTP specification (RFC 2616) is going nicely, albeit slowly. Given...

Since SPDY has surfaced, one of the oft-repeated topics has been its use of TLS; namely that the SPDY guys have said that they’ll require all traffic to go over it. Mike Belshe dives into all of the details...

On a bit of a roll, RFC5861: HTTP Stale Controls has (finally) been published as an Informational RFC. As discussed before in “Two HTTP Caching Extensions,” these are very useful ways to hide latency and errors from your end...

One of the nagging theoretical problems in the Web architecture has been finding so-called “site-wide metadata”; i.e., finding something out about a Web site before you access it. We wrestled with this in P3P way back when, and the TAG...

The Stockholm IETF meeting is shaping up to be an interesting one (and not just because it’s in such a beautiful city). As announced on the mailing list, we are having a HTTPbis working group meeting. It looks like...

A (very) long time ago, I wrote the Cacheability Engine to help people figure out how a Web cache would treat their sites. It has a few bugs, but is generally useful for that purpose. However, as I’ve got...

I had a lovely holiday weekend in Canberra with the family, without Web access. Perhaps I’ll blog about that soon — Canberra being in my opinion one of the nicest overlooked cities in the world — but that will...

Over the past few weeks the Free Software Foundation has had its knickers in a twist about TLS authentication — specifically, its patent encumbrance; That patent in question is claimed by RedPhone Security. RedPhone has given a license to...

Sometimes, it seems like every time somebody has a great idea for a new HTTP header, media type, or pretty much any other protocol element, they do the same thing. Rather than trying to figure out how to fit...

There are lots of new “Web 2.0” specs emerging — many beginning with “o” — that are both exciting and concerning. Exciting because the Web is still evolving and still being applied to new problems, but concerning because the...

Metadata discovery is a nagging problem that’s been hanging around the Web for a while. There have been a few stabs at this problem (including at least one by yours truly), but no real progress. This is both unfortunate...

Huh. The Atom Format RFC has been out for a while, and as one of the authors, I get the odd mail now and again asking a question or just saying “thanks.” In the last week or two, however, there’s...

It’s become quite fashionable for large IT shops to give blanket Royalty-Free licenses for implementation of “core” technologies, such as XML, Web Services and Atom. I’ll refrain from linking to any of them, as the purpose of this post*...

It’s 7am, I’m sitting in the Auckland Koru Club on my way home and reading the minor kerfuffle regarding PATCH with interest. For me, the critical difference between PATCH and POST is generality; PATCH is a generic method (as...

The stale-while-revalidate and stale-if-error extensions aren’t the only fiddling we’ve been doing with the HTTP caching model. Now that Squid 2.7 is starting to see daylight, I can explain about a much more ambitious project — Cache Channels. In...

We use caching extensively inside Yahoo! to improve scalability, latency and availability for back-end HTTP services, as I’ve discussed before. However, there are a few situations where the plain vanilla HTTP caching model doesn’t quite do the trick. Rather...

Back at the W3C Technical Plenary, I argued that Working Groups need to concentrate on making more Web-friendly specifications. Here’s an example of one such lapse causing security problems on today’s Web. Safety in HTTP HTTP methods have a...

It’s become axiomatic in some circles — especially in WS-* land, as well as in many other uses of XML — that the preferred (or only) means of offering extensibility is through URI-based namespaces, along with a flag to...

Microsoft and friends (of the keep your enemy closer variety, I suspect) have submitted WS-Transfer to the W3C. I found the Team comment interesting; e.g., WS-Transfer can therefore be seen as an underlying protocol-independent version of HTTP, i.e. bringing...

It’s been covered before elsewhere, but just a friendly reminder: ‘feed’ URIs are bad for the Web, as are any that are used solely for dispatch (e.g., ‘itms’, ‘pcast’). I’m looking at you, Apple. Interestingly, Apple also supports doing...

I’m intrigued by the JSON effort. While many people (and vendors) have chosen XML for data interchange because it’s not platform- or vendor-specific, these folks have chosen the other path; by leveraging the serialisation of data structures in ECMAScript...

There are MEPs in SOAP and MEPs in WSDL. WS-Addressing doesn't have MEPs, but it does allow you to create patterns of messages.Meanwhile, SOAP has bindings and WSDL has bindings, and WS-Addressing have bindings too. But, a SOAP binding binds an underlying transport, a WSDL binding binds an abstract interface, and an Addressing binding binds abstract properties.That's not the properties in SOAP, by the way, which aren't exactly the same as the properties in WSDL.
