Get complete url in HttpRequestProcessor

Question

I want to get the complete URL in HttpRequestProcessor pipeline. When I hit https://www.abc.com/#section-1, currently args.RequestUrl is not returning the section path. How to get complete URL with section after #.

Answer 1

It's not possible to retrieve the #anchor from the server side in ASP.NET because the browser won't send these anchor fragments to the server. This is a client-side flag to tell the browser to move to a specific place within the page. You can use some JavaScript code in the body onLoad event to check for an anchor and send it back to the server using Ajax.

var anchorValue;
var url = document.location;
var strippedUrl = url.toString().split("#");//or use window.location.hash
if(strippedUrl.Length > 1)
    anchorvalue = strippedUrl[1];

Answer 2

Anchor tags (ex: #my-anchor) aren't considered part of a URL and are not sent to servers. You can read more here: https://stackoverflow.com/questions/3067491/is-the-anchor-part-of-a-url-being-sent-to-a-web-server

For example, see this page: https://www.w3.org/TR/html401/struct/links.html

Click around on the table contents links. Notice that additional requests are not made to the server. They are meant to be used as `"jump links".

If you want to expose the anchor to the server, consider serializing it as a query string: ?my-anchor=anchor-name. From there it's business as usual on the server side: args.RequestUrl.PathAndQuery.
