I find this post How to default to side-by-side view in GitLab, the answer was "not possible".
What about gitweb? Can I default to side-by-side view in GitWeb?

What about gitweb? Can I default to side-by-side view in GitWeb?
Note: default diff view choice is now (since February 2016, GitLab 8.5.0) possible, and retained by a cookie (I have updated my old answer)
I don't see a similar option in gitweb (see gitweb.perl#L7768-L7787)
You can try and use the
?diff_style=sidebyside
url parameter though.
