Re: MOSAIC: little bug (invalid requests)

This has been happing on and off (irregular and not reproducible at
will, but happens enough that you remember it). This was happening both
with 3.8 and now with 4.0

Essentially, double clicking the middle button will open a link in a new
window. But sometimes, the request sent to the server is invalid. A
reload then works.

For instance,
http://webinfo.parl.gc.ca/MembersOfParliament/MainMPsCompleteList.aspx?TimePeriod=Current&Language=E

gives a list of elected MPs and when you double middle click on an MP's
name, you get his profile/contact info in a new window. In order to
reproduce the problem, I have to open perhaps 5 or 6 windows before it
happens. And I have seen this happen on many different web sites over
the years. Don't know why it happens and have no information on what
triggers the problem. It truly seems random.


With a FAILED request TCPTRACE reveals:

Note that the request has just one line followed by a blank line and
does not contain a Host: line which is pretty well required these days
for the web server to know what web site it needs to serve.

This is an HTTP Version 0 request. Mosaic only sends version 0 when
the server did not respond properly to the preceeding HTTP version 1
request. I cannot reproduce the failure, so I cannot tell why the
HTTP version 1 request failed.

I need to see a WWW2 trace (see Debug menu), of the request up to the
version 0 request being sent.
