Hi.
When fetching contents from w3.org, the latency experienced is not
really any problem.
Except when trying to fetch some HTML DTD. This is really slow, and
sometimes the time-out limit in a browser can be surpassed, which
means that the browser regards the server site as not responding.
To better understand these symptoms: ...
*Question*:
- is there a special w3 server dedicated to common DTDs, and this
server has recently become overloaded?
- is it a load-balancing issue?
- or is it the effect of some platform resource usage policy?
It is interesting that DTD should not be any serious bottleneck.
They have a fairly long valid duration -- e.g. for html4/loose.dtd
a header says "Expires: Tue, 24 May 2011 15:21:41 GMT".
The trigger for this question was when a user called the Swedish
Office to ask about "why Internet Explorer could not deliver a page
(from somewhere.com) because the loose.dtd could not be found". I
did look around, and that was when I became aware of the dtd
delivery delays.
Hi Olle,
