adding url at the end of reference

Question

I am using sharelatex for my documentation work. I am doing my reference section with biblatex. While adding my reference all the url that I have used are cited at the beginning. I would like to have these URL towards the end of my reference section.

For eg

1. Article 1,
2. Article 2, 3.URL 4.URL

below is the code I am using.

\usepackage[backend=bibtex,style=numeric,citestyle=numeric-comp]{biblatex}
\addbibresource{references.bib}    
@article{dt3,
    author        = {Leo.},
    title         = {forests.},
    journaltitle  = {45.1},
    year          = {2003},
   %volume        = {911},
    %number        = {14},
    pages         = {5-32},
    %doi           = {http://dx.doi.org/10.1002/andp.19053221004}
}
@online{stack,
author        = {},
    title         = {},
    year          = {},
    url           = {http://stats.stackexchange.com/questions/111968/random-forest-how-to-handle-overfitting},
}

I am new to this platform and any help would be appreciated.

Answer 1

I would suggest a split bibliography: One \printbibliography for non-@online sources and one for @online. A split bibliography makes it clearer why the numbering is different from the usual scheme.

Don't forget the defernumbers=true option if you use a numeric style.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=bibtex, style=numeric-comp, defernumbers=true]{biblatex}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{appleby,
  author  = {Humphrey Appleby},
  title   = {On the Importance of the Civil Service},
  date    = {1980},
}
@online{elk,
  author  = {Anne Elk},
  title   = {A Theory on Brontosauruses},
  date    = {1972},
  url     = {http://example.edu/~elk/bronto.pdf},
  urldate = {2018-09-22},
}
@article{hacker,
  author  = {James Hacker},
  title   = {On Government},
  journal = {Government and Governing},
  volume  = {123},
  number  = {4},
  pages   = {109-123},
  date    = {1981},
}
@online{weisel,
  author  = {Frank Weisel},
  title   = {It Takes Two to Quango},
  date    = {1980},
  url     = {http://example.com/~weisel/quango.pdf},
  urldate = {2018-09-22},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}
\cite{appleby,elk,hacker,weisel}
\printbibliography[nottype=online]
\printbibliography[type=online, title={Online Sources}]
\end{document}
