Hi Thomas,
Thanks a lot for your prompt reply!
I'm not sure I know how to "compile a debug-executable" /-:
However, I was able to workaround this using a while loop that kills a lynx process that is running more than n seconds. This way the 'problematic URL' is being waived out and my script continues (which is what I wanted to achieve here). 

Thanks again!
BR, Royi

not that I recall - the last time there was discussion of timeouts was
a few years ago (and the issue was that the timeout being discussed was
a different feature than that set by the option).

Is it hanging predictably on some urls?  (something I could test...).
If not, you might be able to compile a debug-executable and when it
hangs, use gdb to attach that process and find where it is hanging.

The logic in HTDoConnect (where the option applies) has not changed
much for some time.  Essentially it sets the socket to non-blocking
so that it can do the timeout's.
