'index out of bounds' in httpserver.nim

[jameshfisher]

When running the example at http://force7.de/nimrod/httpserver.html , and accessing localhost from Chromium (specifically), I get an

Error: unhandled exception: index out of bounds [EInvalidIndex]

at the line in httpserver.nim in next() that reads

if cmpIgnoreCase(data[0], "GET") == 0 or cmpIgnoreCase(data[0], "POST") == 0:

This is due to data having no elements, due to buf being the null string. It seems that, rather than sending a request with "GET / HTTP/1.1" as the first line, Chromium is sending a zero-length line. I don't know if this is proper behaviour, but in any case my program should not crash. So I propose changing this to something like

if data.len() == 0 or cmpIgnoreCase(data[0], "GET") == 0 or cmpIgnoreCase(data[0], "POST") == 0:

I changed the code to not use split() at all which should be more efficient anyway. However, httpclient does not work on my Windows VM at all, so I couldn't test it properly on Windows.

No feedback from reporter and EInvalidIndex fixed.
