c# - Authentication encryption or server side verification -


i have set of public apis take in id , parameters. clients (could browsers or mobile phones), each having own int ids, can interact these public apis. of course, don't want situation client changes id , send request screwing things other people thus, when authentication takes place, guid sent client authentication token. subsequent request must include authentication token. on server, end in db match guid id. if match, process can go forward otherwise unauthorizedaccessexception thrown. works fine , dandy.

but of course, problem every operation db up. did caching caching authentication token has own issues (tears tears).

one other way encrypt , pass in query string. when request comes in, have decrypt string see if it's valid. there no free lunch there.

asp.net sets encrypted cookie authentication. view state encrypts things in hidden field. encrypted cookie doesn't work me since i'm passing around json/soap (some clients send json send xml).

if read above, thank , forward input! otherwise , others, the question is , there "best-practice" around dilemma?

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
