How do I send user to a specific location of a html page on third party site?

I agree with rest answers, <a href? is good in that

If that specific location content is in a HTML tag with an id, then you can target that particular id. For ex if the content is in a div :

<div id="bottomrow" class="bottrw">content to be focused</div>

Then your link on the reference HTML paghe should be <a href="http://www.thirdpartysitepagename/#bottomrow" target="_blank">Click here</a>

Hope its clear.

You add # at the end of the URL followed by an element with an id in html.

For example:

If you click on https://www.shadinamrouti.com/codebase#cb-QuickSort you will be scrolled to the QuickSort part of the page because the header of the paragraph is like this:

<h3 id=QuickSort>QuickSort</h3>

i can create specific page using one of programming language like PHP or Java or ASP.Net with any data base like MySql  and use the command

<a href="http://www.ThirdSite.com/page.aspx?parameter=value "> Any Text </a>

Make sure to include the “logout destination” and “time out & redirection” links in the ... If user type is admin, user will be redirected to admin.html page and if user type is ... are logging in for the first time after the site has undergone functional changes

By creating user specific redirects

Create a hyperlink text that interests a user to click on it to the third party site

by anchor link by spicifing  the sction of div id

You can send using jsp by getting the location of the third party site which enables the user to the get the location properly.It is just like the call taxi application such as ola and so on..

use anchor link by specifying the section or div ID in the link anchor

not possible , u must have to used some container
