I update this page on my server but users will not notice the difference until reloading the page.

How can a JavaScript function detect the difference and start reloading the page ?

A solution could be using a timer which reloads the page every second but this causes a lot of traffic?

Have a look at what we've originally implemented here https://dl.orangedox.com/selZdE Notice that the file name extends over the controls, this is what we're trying to fix by using something like the text-overflow css property.

Having a look at the attempts I've tried above

\n\n
    \n
  1. Positioning is correct and removing the middle or the right section allows for the left section to \"grow\" HOWEVER the text overflows in the middle area\n(what we've already implemented
    2. \n
  2. Left box is now bounded to 33% of the screen allowing for the text overflow to be controlled BUT
    3. \n
  3. if the middle box isn't present then the left box doesn't automatically resize to over this available space (since it's explicitly set at 33%)
    4. \n
\n\n

Any ideas on how to better structure this header with overflowing text & controls like this?

I have installed a few packages using opam, such as Core and Batteries. The ocamlinit file is as follows:

I'm not sure what the error is since I followed the installation instructions from the book \"Real World OCaml\".

I also see two messages when I start off utop:

I'm not sure if these are related to the problem but when I do opam list ounit and opam list pipebang it shows them as installed.
