Question

I am trying to develop a web application for which I need to capture a specific user-driven event (such as mouse dblclick) occurring on a different-website page loaded through my website.

What I want to do is :

1. User visits my website – hosted by me.
2. There, user types in any website URL (e.g.: http://www.example.com)
3. That URL page gets loaded as is.
4. When user double-clicks mouse over any link or image from that page, a popup/side-panel is displayed with content related to that particular image or link.

I can do this with a combination of PHP get_page_contents or include-page, and javascript dblclick.
However, when user clicks on any link or submits a form, the control goes to that other website, where I cannot show the side-panel.
I might be able to handle the links by proxifying them when user clicks on any of them. How do I handle forms submission and other stuff ?
I can use a full-featured proxy, but that will be too heavy just for the purpose of capturing the event.

My question is that is there a way to write some kind of light PHP script that sits on my website – that loads other websites contents as is, but lets me capture the mouse-dblclick event to show related-content in the side panel .

I have already searched the internet, but could not find anything.

Any help is really appreciated. Thanks.

This sounds way too complicated to ever get reliably working IMO. Proxifying complex requests on 3rd-party pages? Maybe even with some additional AJAX that you’d have to proxify too? I may be wrong, but I think you’ll go crazy and get swamped with complaints about sites not working.

I don’t know what your web application is supposed to do but I would strongly consider building a Firefox extension (that has much more rights to access and do things on 3rd party sites) or similar.
