iRULE script for S3 type authentication for local EMC Dell S3 Storage

Hi 
I request moderators and experts in this group forum to share your knowledge in iRULE scripting. 

Scenario
We have a DELL EMC storage hardware. S3 object type storage (called S3Storage) has been created in this in-house storage system. to access the S3 storage, the credentials are
Bucket name -  mireport99
User ID -  userid01
Password -  allmipswd
Images stored in the bucket are - Report1.jpg , report99.svg , etc

In the F5, we have a VIP configured webassets.organisation.co.uk-443
This VIP is assigned with a member pool by name webs3images.organisation.co.uk-9021
webs3images.organisation.co.uk-9021 has all the members / virtual machines which make S3Storage.

Question
The requirement is that when the following URL&URI is invoked - webassets.organisation.co.uk/mireport99/Report1.jpg

then the IRULE based on which the VIP behaves; must be able to access webs3images.organisation.co.uk-9021 with all the S3 authentication done i.e., using Bucket name, User ID and Password, must retrieve the image Report1.jpg to the browser. 

HOW DO I GET THIS SCRIPTED PLEASE.

Thanks  and Kind Regards
