Download pages from internet in Parallel and write them in the same order

Hello, I made a simple code that loops through some pages on the internet, downloads them, and saves the content in a text file. I want to make it fast by downloading multiple pages at a time (in parallel), but write them in the same order. for instance, if I download from: [login to view URL] [login to view URL] [login to view URL] [login to view URL] ...... [login to view URL] I want to give the application the option to Async the download (3-5) pages at a time, but write them in the text file in the same order (page 1 content, then page 2 content .... etc.) It is clear that I want the application to be faster than downloading page by page. The code you provided should have a full description in the comments lines, so I can understand the concept of each line and re-use the code in other projects. I have attached a full sample of my code (vb.net 2019), but I hid the URL. Later I can provide the URL for the winner for testing purposes. Best regards,
