Michael Schwarz post a new article about connections limit in Internet Explorer 8. He writes:

«As defined in 1999 (RFC 2616) “clients that use persistent connections should limit the number of simultaneous connections that they maintain to a given server. A single-user client SHOULD NOT maintain more than 2 connections with any server or proxy. A proxy SHOULD use up to 2*N connections to another server or proxy, where N is the number of simultaneously active users. These guidelines are intended to improve HTTP response times and avoid congestion.” Since developers are using AJAX or AJAX-like requests to update a Web page the http limits are discussed more and more.

Currently WinInet limits connections per server with a registry setting (for both, http 1.1 and 1.0). You can simply change the value and have the possibility to connect to more than one server at the time. Other Web browser have limited the concurrent connections to other values. Opera lets you change the value through the Preferences dialog box, look under Advanced –> Network. Firefox users just type about:config in the address bar and hit enter. Then type connections into the filter field. The setting your looking for is network.http.max-persistent-connections-per-server.»

Kilian Valkhoff post an articleabout current state of modern browsers. He writes:

«A long time ago, there raged a war. At the time I was too young to notice much of it, but there were a great number of casualties. While the two major forced kept making new rules, the innocent inhabitants were forced to pick a side and fight along.

I am, obviously, talking about the Browser Wars of lore, between Internet Explorer and Netscape. At the time, both browsers were rapidly innovating and adding new features, — however, they both implemented different stuff, never the same thing in the same way. This caused web developers to develop for one of the two, two different sites for two browsers, or one sub-standard website that worked in both.»

There is an intresting artile about the new browser fromAT&T written by Jacque Cheng. He writes:

«AT&T has opened up a private beta of its new, hyper-visual web browser named Pogo. Yes, you read that right—AT&T is diving into the web browser market with a new creation of its own, based on Mozilla and 3D technology from Vizible, a Canada-based company that AT&T has invested in. The goal is to create a web browsing experience that is more robust than the crufty old browsers that we have all grown accustomed to. The software is not yet open to the public, but we had an opportunity to test out Pogo and see what it was all about.

First off, Pogo is Windows-only, and AT&T makes no indication that it will be available for the Mac anytime soon (or ever). It requires Windows XP SP2 or later or Windows Vista, and its minimum hardware are surprisingly steep: a 1.6GHz processor, 2GB of RAM, and a video card with at least 256MB of VRAM. Seem like a bit much for a web browser? It is, and as we found out, these requirements posed some major challenges for us during our testing.»

Dave Hyatt write an article about the supports gradiernts in WebKit. He writes:

«WebKit now supports gradients specified in CSS. There are two types of gradients: linear gradients and radial gradients.

The syntax is as follows:

-webkit-gradient(<type>, <point> [, <radius>]?, <point> [, <radius>]? [, <stop>]*)

The type of a gradient is either linear or radial.

John Resig write about thed futures of the browsers in his blog. He tells about some intresting predictions on 2008-2009 years:

«For example, I would probably rate the current, 2008, list as follows (in order of cost-benefit):

• IE 6

• IE 7

• Firefox 2

• Safari 2 & Safari 3 (tie)

• -- common cut-off point --

• IE 5.5

• Opera 9.2

Starting in 2009 I predict that the list will be similar to the following:

• IE 7

• IE 6

• Firefox 3

• Safari 3

• -- common cut-off point --

• Opera 9.5

The AJAXWorld Magazine has revealed some details about the next version of Microsoft Internet Explorer. Here is small excert from interview with IE general manager Dean Hachamovitch -

"As I’ve walked different people through the plan, I’ve gotten 'Does it have feature X?' “When is the beta?' 'When does it release' and even the more thoughtful 'What are you trying to accomplish with this release?'

You will hear a lot more from us soon on this blog and in other places."
