URL protection

Serves to protect the URL, so third parties cannot modify its content. This has significance in the expenses of CU and other service specific aspects (e.g.: full size images are behind a paywall, etc.)

Types

Generated by an API key

The simple form of generating.

• URL starts with s-b3:

Generated by an access token

More complex, but more secure and function-rich method of generating URL.

• URL starts with s-token2:
• number of usage can be specified
• date of expiration can be specified
• option of HTTP authentication
• each usage have a minimal CU cost

Tips

• it is usually suggested to enable and and use an obligatory cloud encryption
• if there is not obligatory URL protection enabled, then the function of protection will be skipped
• can be generated by the hash program codes of the protection and cannot be manually specified

Limitations

• Due to the fact that access token requests are counted, it is not feasible to service multiple thousands of requests / second (however, the capacity can be multiplied by using multiple access tokens simultaneously)
• You can only generate and manage Access Tokens from API-s
• If you are using a CDN, the available functionality of the access token may be fully or partially reduced, because of the nature of CDN network services.
