Aah, I know what is happening.
When you send a POST request and not read the input, it gets available
to the next request.
For example consider the following 2 requests.
POST /path1 HTTP/1.1
k1: v1
k2: v2
rndval=1234
GET /path2 HTTP/1.1
k1: v1
k2:v2
Since the data in POST request is not read, the second request's
method becomes rndval=1234GET.
Even I noticed this once. This happens only with cherrypy webserver
and not with lighttpd or apache.
If you make sure you read all the given input data, it will be OK. You
may add the following unloadhook.
web.unloadhooks['input'] = web.input
