I have a cryptocurrency exchange rate calculator, in which, for example, it is worth converting 100 ETH to USD. After clicking the Learn course button, I need to open a page with the link https://www.example.com/convert/eth/usd/100 That is, the value from the calculator should be entered into the link and the page should open accordingly. The page itself, it is logical that it will not be on the site, because I will not be able to create pages for all the numbers at the end of link. I saw this on exchangers, you enter the amount, it opens a page in which there is your amount in the link and breadcrumbs. As I understand it, pages are created dynamically or some kind of template is used, but I don’t understand how to do this? Moreover, if you change the value of 100 to any other directly in the link, the page should open on which the new value will be used. Help, I'm struggling, I can't find a solution...
