This one kept me busy for a while and I although could find similar questions none of the solutions worked.

Using template partials, gather the page content then send though (via embed) to a master wrapper template. This site has 'pages' where the URL should identify a unique entry, but EE tries it's best to show something, adding require_entry in the Channel tag should trigger no_results if an entry can't be found.

{no_results} works as expected when trying the channel:entries tag (below) outside of stash. Looking at stash docs, unprefix is specifically for this scenario. The below code does work.

{exp:stash:set
    name        = "st_page_content"
    parse_tags  = "yes"
    unprefix    = "my_prefix"
}
    {exp:channel:entries
            channel         = "channel_short_name"
            limit           = "1"
            require_entry   = "yes"
        }

    <p>{title}</p>

    {if my_prefix:no_results}<p>no results</p>{/if}

    {/exp:channel:entries}
{/exp:stash:set}

But it doesn't work when stashing multiple variables between 1 stash tag pair. Eg. no_results is not stored in st_page_content:

{exp:stash:set
    name        = "st_page_content"
    parse_tags  = "yes"
    unprefix    = "my_prefix"
}

    {stash:st_entry_id}{entry_id}{/stash:st_entry_id}

    {stash:st_page_content}

        {exp:channel:entries
                channel         = "channel_short_name"
                limit           = "1"
                require_entry   = "yes"
            }

        <p>{title}</p>

        {if my_prefix:no_results}<p>no results</p>{/if}

        {/exp:channel:entries}

    {/stash:st_page_content}

{/exp:stash:set}

I feel the example code in the question should work but it doesn't. Here's a solution. I understand why it does work, but it seems wrong.

{exp:stash:set
    name        = "st_page_content"
    parse_tags  = "yes"
    unprefix    = "my_prefix"
}

    {stash:st_entry_id}{entry_id}{/stash:st_entry_id}

    {stash:st_page_content}

        {exp:channel:entries
                channel         = "channel_short_name"
                limit           = "1"
                require_entry   = "yes"
            }

        <p>{title}</p>

        {if my_prefix:no_results}<p>no results</p>{/if}

        {/exp:channel:entries}

    {/stash:st_page_content}

    {if stash_prefix:no_results}
        {stash:st_page_content}{redirect="404"}{/stash:st_page_content}
    {/if}

{/exp:stash:set}

If EE can't find an entry, anything not inside no_results is discarded. So all that's left inside the stash:set is:

{if stash_prefix:no_results}
    {stash:st_page_content}{redirect="404"}{/stash:st_page_content}
{/if}

And now st_page_content will store just the no_results content. It seems wrong to be setting the same variable twice but due to EEs parse order there's only ever one instance of st_page_content.

After getting feedback from Mark, there's another solution, that's really not that different! https://twitter.com/croxton/status/573949167824953344

that's one way to do it. But you should be able to use {exp:stash:not_found} inside the first conditional to return your 404.

https://github.com/croxton/Stash/wiki/%7Bexp:stash:not_found%7D#advanced-example

I've tried this and it does not work:

{exp:stash:set
    name        = "st_page_content"
    parse_tags  = "yes"
    unprefix    = "my_prefix"
}

    {stash:st_entry_id}{entry_id}{/stash:st_entry_id}

    {stash:st_page_content}

        {exp:channel:entries
                channel         = "channel_short_name"
                limit           = "1"
                require_entry   = "yes"
            }

        <p>{title}</p>

        {if my_prefix:no_results}<p>no results</p>{/if}

        {/exp:channel:entries}

        {if stash_prefix:no_results}
            {exp:stash:not_found}
        {/if}

    {/stash:st_page_content}

{/exp:stash:set}

Putting the {exp:stash:not_found} in the first tag pair ({stash:st_entry_id}) doesn't work either.

But similar to my original solution wrapping {exp:stash:not_found} with the variable tag pair does work. This is exactly the same solution as using {redirect="404"} but maybe EEs redirect tag will cause problems in other circumstances.

Alternative solution:

{exp:stash:set
    name        = "st_page_content"
    parse_tags  = "yes"
    unprefix    = "my_prefix"
}

    {stash:st_entry_id}{entry_id}{/stash:st_entry_id}

    {stash:st_page_content}

        {exp:channel:entries
                channel         = "channel_short_name"
                limit           = "1"
                require_entry   = "yes"
            }

        <p>{title}</p>

        {if my_prefix:no_results}<p>no results</p>{/if}

        {/exp:channel:entries}

    {/stash:st_page_content}

    {if stash_prefix:no_results}
        {stash:st_page_content}{exp:stash:not_found}{/stash:st_page_content}
    {/if}

{/exp:stash:set}
