How to create custom URL to access the IPFS content

I successfully created IPFS private network with 2 bootstrap servers. Using the readonly 8080 port. I proxied it and able to access the content via.
http://domainname.com/content/

Now, I want to add the filename or any logicalname next to the hash content for example,
http://domainname.com/content//filename.json

Please let me know what is the right method to do it. If you can share any article link that would be help ful.

Thanks
