Comment:
I can reproduce this - my users could :(
Given the following view and lighty+fastcgi+prefork:
{{{
def do_random(request):
return HttpResponse(random.sample('ABCDEFGHIJKLMNOPQRSTUVWXYZ', 5))
}}}
Produces in subsequent requests:
{{{
XDQIU AJMNL JIQXN XDQIU IROXL AJMNL YAPJL CUYOK ODKLA JIQXN WACZR IROXL
CYUJE SNQLX YAPJL CUYOK UMOWL ODKLA PIXQG WACZR CYUJE
}}}
which is *NOT* random.
Applying the patch, the same view produces
{{{
QBLDN THPXF VSJQB RIPTF EZQRL OSNZY HQSOB VJSED HQBTO UTOJI VSTFY NHPBY
QMITZ WJGZB QVDRN QCIOT GWYVQ RGZHE TXHKI
}}}
which seems fairly random.
