| final_resource - The location of the last redirect. |

| For each number i between 1 and |redirect_count| we have the following optional parameters: |

| origin{{i}} - The origin of the ith redirect (i+1 response). Default is location.origin. |
| Note that the origin of the initial request cannot be controlled here |
| and the Timing-Allow-Origin header of the final response cannot be controlled here. |

| Example: redirect_count=2&final_resource=miau.png&tao1=* |

| Note: |step| is used internally to track the current redirect number. |
