session

问题 I have a view that takes logged in user input then runs a function to produce a report. The result is returned in an HTML page. I render the report to PDF as well. I create a PDF with the content from my function and save it in some folder on the server. I don't want to have my server filled with files from every run, so I create a temporary folder (in tmpfs) for each user when they log in and save the path in their session, which is not permanent. session['temp_path'] = '/dev/shm/<random

问题 I know about the sessions in C# and how to define them as well. But today I heard a term Lock-free sessions. I googled it but did not get any answer exactly matching to my question. Can anyone please explain something about lock-free sessions in C# and how to write a code for them? 回答1: Here is some content from msdn section Concurrent Request and Session State Access to ASP.NET session state is exclusive per session, which means that if two different users make concurrent requests, access to

Run the app and open a

问题 Everything in italics is the original post, edits below are non-italicized I am writing in C# using ASP.NET 4.0. I am authenticating user credentials via SQL lookup and if valid I am storing the username in a session variable then redirecting the user back to the main page. Pretty simple. if (!db.isValidLogin(userName, passWord)) { //invalid login, show it! //just some code to tell the user invalid credentials } else { //show login successful! //update some items on the screen Session[

问题 im in trouble with implemenetation of a service layer, i think i did not understand this concept very well. In a DAO implementation i can write all CRUD logic for a specific technology and entity (for example hibernate and User table), and in a service layer we use a DAO for all data operation for the entity in DAO (like getUser, loginUser, etc..) is this ok? If this is ok i have a simple question, can i handle database connection (or in case of hibernate, session and transaction) within

问题 I plan to extend the default sessionstore by adding an account_id, for this I followed this link extending-database-backed-session-engines, but the account_id is not being created on migrate. The application is located in app folder. In ./settings.py . I have: INSTALLED_APPS = ( 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.messages', 'django.contrib.staticfiles', 'app' ) According to this link Extending the Session Middleware I have: SESSION

问题 Im Using AddDistributedMemoryCache for session in my application and keep losing my session in IIS. the program Session works well in Visual Studio Debug mode. this is Startup Code : public void ConfigureServices(IServiceCollection services) { // Add framework services. services.AddSingleton<IActionContextAccessor, ActionContextAccessor>(); services.AddOptions(); services.Configure<AppSettings>(Configuration.GetSection("AppSettings")); services.AddMvc(); services.AddDistributedMemoryCache();

问题 I am currently using window.sessionStorage to store a uniquely generated session ID. This ID is passed to all ajax calls to the server and persists across page navigation and reloads. This seems to work perfectly for my target browsers, with one caveat: the duplicate tab functionality in Chrome. Duplicating the tab copies the session storage to the new tab. When the new tab loads and communicates with the server, it now has the same "unique" identifier as the duplicated target tab. Are there
