Graham,
Thank you for your reply.
So, I used the debugging techniques like this:
in input filter
###########################
from mod_python import apache,Cookie
def inputfilter(filter):
filter.req.log_error('Running inputfilter')
filter.req.log_error('Setting myflag..')
filter.req.myflag = True
filter.req.log_error('myflag was set to:')
filter.req.log_error(`filter.req.myflag`)
if filter.req.method != 'POST':
filter.pass_on()
return
s = filter.read()
while s:
f.write(s)
f.flush()
filter.write(s)
filter.flush()
s = filter.read()
if s is None:
filter.close()
f.close()
########################
in handler
##########################
def handler(req):
if req.method == 'GET':
......
else:
if req.method == 'POST':
req.log_error('Myhandler')
req.log_error('MyHandler, in POST request, has myflag')
req.log_error(`req.myflag`)
....
....
#######################
and here is a part of error log
..

Where can be a problem? What shall I try?
Can you see any mistake I make?
Thank you again for help
