Configuration:

• Web browser and its version: chrome 107.0.5304.110 (Official Build) (arm64)
• Operating system and its version: Macos 13
• PDF.js version: 2.16
• Is a browser extension: No

Steps to reproduce the problem:

1. Open any large pdf around more than 100mb file
2. In network you can see that it is downloading whole chunks instead of particular chunk range

What is the expected behavior? (add screenshot)

I'm using the above configuration

I have done all the recommended step to lazy load the pdf page

• Linearized the PDF
• server supports range request

For first page it is load the first chunk properly but for the last page it is downloading the whole pdf as chunk.

(If recommended)
I'm ready to save the page wise range bytes in server so that I can give proper bytes while loading pdf

What went wrong? (add screenshot)

I want to view the page fast as much as I can but the chunk range not downloading the specific chunk to render the page quickly

Given the overall lack of actionable details, i.e. no PDF document nor runnable test-case provided, there's unfortunately nothing anyone can do to help! Please keep in mind that this is first and foremost an open-source bug tracker, rather than a support forum, and that all issues must be easily actionable.

Most likely this is just a duplicate of #15457, however #14570 (comment) could possibly be relevant as well (depending on the PDF document used).
