阅读更多关于 Flask client-side sessions

问题 Starting to learn Python's Flask web app framework, still on the learning curve, so please bear with me. I am wondering how appropriate are the client-side sessions for secure web application purposes. From what it seems, there are some serious concerns: Since all the session variables are serialized and encoded in a cookie one should be careful with how much data they store there, in order to keep the size of http data travelling back and forth in reasonable size. I'm not sure if identical

grails session creation, on how to prevent it

阅读更多关于 grails session creation, on how to prevent it

in the last line in the following bug report https://github.com/grails/grails-core/issues/5296 it is stated that; In an ideal world, it would be possible to turn off HttpSession creation for a whole Controller (all actions) and also turn them off for a particular set of actions. This is however, a quite old bugreport, so my question is: is this possible in an upcoming or todays version (1.3.7) of grails? If not, shouldn't it be? The reason i seek this kind of behavior is due to development of RESTful API's in grails, where the very nature of REST is stateless . Grails does not create a session

问题 Does anyone know how PHP maps session IDs to $_SESSION arrays? In other words, given session ID x, where does PHP pull the values from to populate the $_SESSION array? And given a session ID and the url it came from, is there any possibility of someone being able to gain access to the values in the $_SESSION array? 回答1: By default, PHP uses the files session handler. These files are stored based on the session.save_path setting, but defaults to the system's temp directory (a highly insecure

Why PHP session is deleted on page reload?

阅读更多关于 Why PHP session is deleted on page reload?

问题 So I've this problem that, when I'm on the page not doing anything for some time, after I reload the page $_SESSION is cleared. I checked the code and it does not have any unset() functions or anything else what could clear the $_SESSION variable. Any ideas why is it happening? Edit: In case if I want to make the session live till the browser is closed what should I do? I don't understand it as the gc checks if session is expired on session_start , but I can't modify the session data before
