Cookies and browser storage
Keep these details in mind. Local storage keeps data in the browser and is not automatically attached to each server request. This page explains the storage used by the built-in features of it9blog.com. Both mechanisms can be managed through your browser's site-data settings. A cookie is a small value a browser can send back with matching website requests.
The contact-form cookie
The key details are straightforward. The FAQ submission flow uses a cookie named spider_csrf to support request verification. The cookie contains a random value rather than your question or email address. The cookie is scoped to /api/ and expires after about one hour. The application marks this cookie HttpOnly and SameSite Strict, and uses the Secure flag on HTTPS.
Protecting a submission
The key details are straightforward. The token expires after approximately one hour. The server checks the form cookie together with a signed token when a question is sent. If the form expires, reload the page and submit again. The check helps reject requests that did not originate from the protected form flow.
Local game keys
Keep these details in mind. Game progress is stored under local-storage keys beginning with spider-v1:game-. One suit, two suits and four suits use separate saved game records. A saved record includes the card layout and recent undo history so that play can resume. Turning off game saving removes those application game records.
Statistics keys
These records stay in the current browser profile and domain. Keys beginning with spider-v1:stats- hold game statistics for the selected difficulty. Statistics can include started games, recorded wins and the best winning move count. Clearing game data removes the statistics stored by this application.
Preferences storage
Keep these details in mind. The clear-data action switches saving and sound off after removing earlier records. The site reads these choices when the game or settings page opens. The spider-v1:preferences key stores the game-saving and sound choices. Preference storage is used to remember your choices on later visits in the same browser.
Duration of local storage
On this website, the following points apply. The site cannot restore local progress after that browser data has been cleared. Browser local storage does not have an automatic cookie-style expiration date. The game records remain until the application, you or your browser removes them. Private browsing may discard records when its session ends.
Manage or block storage
Here is what to know. Privacy & Cookie Settings provides controls for this application's game records and preferences. Your browser can also remove this domain's cookies and local storage. Blocking local storage can stop progress from being retained between visits. Blocking the form cookie can prevent a contact submission from being accepted.
External share services
On this website, the following points apply. The built-in share buttons are links rather than embedded social-media widgets. The built-in application contains no advertising or analytics integration. Activating a share link opens the selected service with the current page information. An external service can apply its own cookie and storage practices on its destination page.
Questions about storage
Here is what to know. Clearing browser storage does not erase a message already saved on the server. The operator should revise this policy whenever the storage used by the site changes. The Privacy Policy describes contact submissions and technical request information in more detail. Contact [email protected] for a question about this website's storage practices.
