R devel - Sep 2009 - Problems connecting to httpd help server with some browsers

Hello, 

sorry to provide only very little testing, but with the release date nearing, 
I thought it better to report this quickly than to wait for an uncertain 
period until I find more time.

I'm observing strange problems connecting to the httpd help server with 
konqueror (KDE 4.3.1):

options (help_type="html")
options (browser="konqueror")
help ("print")

The first page opens in a konqueror window as expected. However, clicking on 
any links does not have any result. Konqueror just says "waiting for
reply"
forever. There does not even seem to be a timeout. Pointing the same browser 
instance to some other url works fine.

Trying to use lynx as a browser (since it's a terminal browser, you need
open
lynx in a separate terminal and point it to the httpd help server manually) 
causes lynx to become unresponsive.

Both konqueror and lynx are able to browse the static html files just fine.

Firefox and Opera work fine with the httpd server on the same computer.

Does anybody else see similar symptoms?

Regards
Thomas

Yes, good thinking :).

I don't have konqueror at hand, so I have tested and fixed the lynx  
case (lynx is acting as an HTTP/1.0 client and expects non-persistent  
connection). With some luck the fix may solve the konqueror issue as  
well (although I'd be a bit surprised if konqueror was not 1.1- 
capable..).

Thanks,
Simon
