Adding new query parameter to hyperlinks dynamically

Question

I have several hyperlinks in my homepage. I would like to add a query parameter at the end of each hyperlink dynamically.

For example;

<a href="detail.aspx?id=2" target="_blank" >xyz</a>
<a href="detail.aspx?cid=5" target="_blank" >pqr</a>

will be converted to

<a href="detail.aspx?id=2&redirectFrom=hp" target="_blank" >xyz</a>
<a href="detail.aspx?cid=5&redirectFrom=hp" target="_blank" >pqr</a>

a new query parameter " redirectFrom " with value have been added to the converted hyperlinks.

How I can achieve it using ASP.net C#?

Maybe you can use Request.UrlReferrer.AbsolutePath instead of dynamically modifying each Link in your page. Please make sure whether or not UrlReferrer is null or not with every Request.

Good luck!
