The small but very fine browser Opera, which has a loyal customer base, has a new beta out.

You can get it at their site.

Two good resources are also the feature request site and the known issues.

Btw, Opera will also ship as the default browser for Psion PDAs in the future.

It supports XML! (more

about XML from Opera)

From another release:

" Opera 4.0 Upgrades File Exchange: Includes HTTP 1.1


HTTP 1.1 is the name of the latest version and it is included in Opera 4.0.

doing more, doing it faster

Who cares that the language of Web communication is changing? You do -- Because

this version of HTTP provides higher end-user performance.

It does more and it does it faster. This is great for web surfers and especially

good for Opera users, because Opera 4.0 has HTTP 1.1.

prevents eavesdropping of passwords

It is also more secure. HTTP 1.1 is more secure because while you authenticate

yourself, it does not allow eavesdropping.

This is an important step, increasing security on the web.

give me something faster

Security is great. I’m glad my passwords aren’t being passed around.

Yes, and Opera is very secure (we’ll save that for another time).

Opera with HTTP 1.1 is even faster.

HTTP 1.1 is faster because it allows persistent connections. Persistent connections

benefit networks and end-users.

HTTP 1.1 increases performance by allowing persistent connections; pipelining,

caching, and IP address preservation.


Pipelining allows Opera to make multiple requests without waiting for an answer.

Basically it is the difference between calling someone multiple times asking

for different items versus calling once with a list.

A list is obviously more efficient!

Chunking is the splitting up of documents. Once chunked the document can be

sent over a persistent connection through a pipeline.

Each chunk is a known length so by splitting up the document in chunks even

documents that have no known length can be sent.

headers used for cache verification have been expanded

There is more cache control. Opera is served more details. These details expand

the caching capabilities because they allow more information to be held.

Information like how old a document is, how long before it should be refreshed,

or if it should be checked every time.

HTTP 1.1 Under the Hood

HTTP 1.1 has furthered the speed of Opera.

Opera is serving you documents faster, and with HTTP 1.1 increasing the general

efficiency of the Web.

It is relieving congestion and utilizing better methods of caching.

Additionally, it is providing a little extra security when sending your passwords.

HTTP 1.1 is a great item to have under the hood in Opera 4.0."

Sounds great, doesn't it?

Check it out.

Feel free to disagree, but I think Opera did more for standards then MS and Netscaper/AOL

together the last two years.

Wolfgang .wolf Bromberger has been around online since 1996. He started to get into web design after he and some other students developed a concept for the online presence of their home town, Salzburg in Austria, a site Bill Gates used years later as a good example of e-government (as still not nearly all points of the concept have been made reality, .wolf disagrees).
Being interested in search engines and information systems, .wolf specialized in search engine optimization, online promotion and analysis.

He is always interested in learning new programming or other web related skills, when time permits.
