Hi!

This sounds like a bug that was fixed in inets-4.7.16.
Could you make sure you have that version, and if there is
still a problem 
contact us again.

Ok, then we will have to investigate.

I have  a problem  recreating the  situation as  the link
seems to be 
redirected
to a https link, and I have no direct Internet access and
alas https 
through a proxy
is  not supported as yet by the client. (The reason is that 
ssl has not 
had the necessary API functions to implement it. It will
soon though.)  
Well anyway could you do:

http:set_options([{verbose, trace}]).
**http:request (get, { "http://mitch-al
ex.blogspot.com/", [] }, [ { 
timeout, 1000 } ], []).

And  then send us the result.
