Data Hashing: First, generate a unique hash value for each data URL. This can be achieved by using common hash algorithms (such as SHA-256). The hash value ensures that each data URL has a unique identifier.\\n\\n2. Storage and Query: Store all processed URLs and their corresponding hash values on the server-side. When a new data URL is received, the server will calculate its hash value.\\n\\n3. Compare Hash Values: Compare the hash value of the new URL with the stored hash values on the server. If a match is found, it indicates that the URL has already been processed and is a duplicate.\\n\\n4. Deny Duplicates: If a duplicate is detected, deny the request to process the URL and provide an appropriate error message to the user.\\n\\nBy implementing these steps, you can"}]}],"pr":"cc9dfb3af995c053b2104f560b7dd945a74e9f6c5effcf97c2efc333b05070e2"}
