Question

Is the iTextSharp DLL free to use and redistribute with my web application project which i will be selling?

Solution 1

Yes, as long as you don't try to sell it to your customer as your own product (;-)), you're free to use and deploy it as part of your own app.

Update 02/06/2011:
iText appears to now have a strong copyleft license (AGPL). This means that you cannot use it as part of a commercial product...

Solution 2

Version 5.0.0 and up is licensed under the AGPL (strong copyleft).
Version 4.1.6 and previous are still licensed under the MPL/LGPL (weak copyleft).

So for a commercial product you'll almost certainly want to stick with 4.1.6 or previous.

Here's an archived unofficial citation.

Solution 3

Yes, as long as you are just dynamically linking it under the LGPL.

Edit: See accepted answer, iText now uses a strong copyleft licence which requires you to release your source code if you use it.
