I saw you already took an extensive answer from Jürgen, but you could make
your own function to work, by simple using "cd", to change directory and
then let vim do the rest, without using extra functions.

To make your function a little bit more robust, you can use a try/catch
to see if vim can change to that directory, or you can use for the same
purpose the isdirectory() vim function to see if the directory actual
exists, so you can gracefully handle an error, like:

function! VS()
try
cd ~/public_html/jeditux.home/vim_sessions/
catch /^Vim\%((\a\+)\)\=:E344/
echo "Caught an exception\nVIM EXCEPTION: ".v:exception
return 1
endtry
let ans = input('Session name: ', '', 'file')
execute ':source '.ans
endfunction
