<p style="margin:1.2em 0px!important">Yes. Or you can add custom javascript to the page to take action based on the parameters once the page is loaded. But again, I wouldn’t recommend doing this, because it may conflict with server changes in the future. If you go this route, I would suggest using <code style="font-size:0.85em;font-family:Consolas,Inconsolata,Courier,monospace;margin:0px 0.15em;padding:0px 0.3em;white-space:nowrap;border:1px solid rgb(234,234,234);border-top-left-radius:3px;border-top-right-radius:3px;border-bottom-right-radius:3px;border-bottom-left-radius:3px;display:inline;background-color:rgb(248,248,248)">#</code> instead of <code style="font-size:0.85em;font-family:Consolas,Inconsolata,Courier,monospace;margin:0px 0.15em;padding:0px 0.3em;white-space:nowrap;border:1px solid rgb(234,234,234);border-top-left-radius:3px;border-top-right-radius:3px;border-bottom-right-radius:3px;border-bottom-left-radius:3px;display:inline;background-color:rgb(248,248,248)">?</code>, since it would really be client-side only information.</p>

<p style="margin:1.2em 0px!important">No. The HTML/Javascript context of the page and notebook server are strongly decoupled from the Python environment of the Kernel. We have no plan to change this.</p>

<p style="margin:1.2em 0px!important">At least a few:</p>
<ul style="margin:1.2em 0px;padding-left:2em">
<li style="margin:0.5em 0px">the NotebookHandler, which renders the notebook page, which will receive the URL with parameters, but is not the URL that starts the kernel.</li>
<li style="margin:0.5em 0px">the KernelManager, which starts the kernel, which would need to be told about these parameters</li>
<li style="margin:0.5em 0px">possibly the Kernel itself, for taking the actual actions you wish these parameters to imply in the kernel process.</li>
</ul>
<p style="margin:1.2em 0px!important">Depending on how much javascript you customize, there are probably a few combinations of classes to modify.</p>
<p style="margin:1.2em 0px!important">Can we back up a bit, and ask what you want to accomplish by passing these parameters? There may be a simpler solution than subclassing the entire notebook server.</p>

<div><br><br><div dir="ltr">You can do this, but I wouldn't recommend it. The parameters will only be available to the HTML/JS in the notebook page, and not the Python code on the kernel.
