I use delphi + chromium to do webApp operations automation. The webApp is built with high class components that are inoperable with javascript (that I can execute from the delphi level). After hours of digging and consultations with web specialists, we found a way to handle my problem, by altering webApp's source code BEFORE its java scripts start to process it.

So... what I'm looking for is an event that will trigger when component downloaded the code BUT BEFORE it started processing it AND WITH OPTION to alter the page's code BEFORE processing started.

General schema of website operation looks like this

1. Browser requests a website
2. Server-side rendering
3. Source code transmission
4. Browser gets the code ----------------- <<<<<<<< ---------- I need to cut in here with my source code changes
5. Browser loads it to engine
6. Browser starts all javascrips

Any ideas?

Best regards M.
