To cache an image and PDF in a Redis server, you can use the SET command to store the binary data of the image and PDF file in Redis. Here is a general outline of how to do this:

  1. Convert the image and PDF file into binary data.
  2. Use the SET command to store the binary data in Redis along with a key that identifies the file.


Example:

1
2
SET image_key "binary_data_of_image"
SET pdf_key "binary_data_of_pdf"


  1. When you want to retrieve the image or PDF file from Redis, you can use the GET command to retrieve the binary data and then convert it back into the original file format.


Example:

1
2
GET image_key
GET pdf_key


  1. Make sure to set an appropriate expiration time using the EXPIRE command if you want the cached files to be automatically deleted after a certain period of time.


Example:

1
2
EXPIRE image_key 3600  // expire after 1 hour
EXPIRE pdf_key 86400  // expire after 1 day


By following these steps, you can effectively cache an image and PDF file in a Redis server for faster retrieval and improved performance.
