Get full URL with hash to use as ReturnUrl

问题

I have such URL

localhost/Login/LogOn?ReturnUrl=/#&q=my%20search%20word&f=1//447044365|2//4

I need to get hash parameters to navigate in the application after authentication.

I try to catch it like this

<input name="returnUrl" value="<%= ViewContext.HttpContext.Request.Url.PathAndQuery %>" type="hidden" />

But result is

/Login/LogOn?ReturnUrl=/

I tried to take away "/#" in the URL, then I get whole URL. But I need to use this URL as it is.

Why was URL cutted?

回答1:

The browser does not send the hash fragment to the server. It used on the client-side only. If you need it you will have to access it through client-side script.
