Is anyone using the http module to do largish transfers?

Is anyone using the http module to do largish transfers?

[Alan Perry]

Hi,

I am trying to debug a problem involving largish HTTP data transfers 
(around 80M).  I have no problem transferring around 3M with the grub 
http module.  Has anyone here observed a similar issue or is this not a 
problem for others and I should be looking for the problem somewhere 
other than the http module?

Thanks,

alan

I did a quick test and was able to do "initrd (http)/initrd" for ~90MB
file using current git. This is under QEMU. Physical hardware may be
different.

OK, knowing that it works in some instances is good.  As I have been 
digging into the problem, it seems to be somewhere other than http. I 
would elaborate further, but I am still working through why the code is 
doing what I see on the network.

Another question about the http module.  http_establish() builds a GET 
request that may have a Content-Range header.  However, looking at the 
HTTP/1.1 RFCs, Content-Range is something that appears in a status 206 
response, not in a request.  The http module shouldn't insert this 
header, should it?

Where do you see it?

My mistake - looks like this has been changed since I last updated my 
local repo.
