Rebase "web-123-my-branch" onto master:

if you're the only person who is working on a branch...

$ git checkout web-123-my-branch # make sure you're on the right branch
$ git fetch # update remote refs
$ git rebase origin/master # perform the rebase onto the current state of master
  # for each conflict, edit file, resolve conflicts, git add -u <file>, git rebase --continue
$ git push -f origin web-123-my-branch # overwrite remote branch with newly rebase branch
