**Option 1 (Focus on challenges and solution):**

* **How to Reference Images in CSS Files from Different Directories in Symfony 2?** 

**Option 2 (Highlighting specific issue):**

Path of Assets in CSS Files in Symfony 2

In the context of Symfony 2, there have been difficulties in referencing images in CSS files from different directory structures. Consider the following directory structure:

...
+-src/
| +-MyCompany/
|   +-MyBundle/
|     +-Resources/
|       +-assets/
|         +-css/
|           +-stylesheets...
+-web/
| +-images/
|   +-images...
...

The challenge arises when attempting to reference images in stylesheets while adhering to the best practices of keeping original CSS files in the asset directory (/src/MyCompany/MyBundle/Resources/assets/css/) and images in the public directory (/web/images/).

Initial Solutions

Initial attempts included using absolute paths and Assetic with the "cssrewrite" filter. However, these solutions proved ineffective.

Current Solution

The current solution involves utilizing relative paths in CSS files and adjusting twig accordingly. Instead of using absolute paths, images are referenced as follows:

url("../images/myimage.png")

This solution works in the production environment but encounters an issue in the development environment, resulting in a NotFoundHttpException.

Improved Solution

To overcome this issue, the improved solution involves having the CSS files in a public directory and using the asset function to reference images. Additionally, the original CSS files can be removed after the assetic:dump command. This allows for the desired behavior of keeping original CSS files private while still referencing images correctly.

Final Winner

Upon testing various methods, the best solution emerges as using the asset function with CSS files located in a public directory. This approach adheres to the need to keep original CSS files unpublished while ensuring proper referencing of images.

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
