Need a Powershell script to change css code
Posted on 2014-07-09
Hi Experts,
I'm quiet new to PowerShell scripting. What I need is the following;
I've got a simple HTML / CSS website. The site shows some computer icons that users can click on to start a RDP session to a workstation. Below each icon I want the network status of that specific workstation shown.
So the script needs to ping the workstations from, for example a txt file with a list of ip addresses, and then show the text 'online' or 'offline' below the icons of that workstations. The background color must be green or red.
Can I build a css file that creates a class for every PC that's in the list in the txt file? I know I asked this here before, but I haven't found a good solution yet.

I don't this this will ever work properly mate...
If I well understand you you want to change the CSS to reflect the servers status instead of doing it server-side right?
The main problem I see here is actually related with the browsers cache.
If the name of the CSS file doesn't change, the browser won't download it again, sometime not even with a Ctrl-F5 (IE is a bit unstable on this and Opera you can well forget about it).
So, even if you change the CSS file the browser won't pick it or you'll never be 100% sure if he picked it or not.
Your most reliable way to implement this is server side or client-side with AJAX calls and timers.

I don't know but It won't make much difference anyway mate.
You can't neither easily nor reliably control the way browsers reload their resources upon refresh.
Sure there are a lot of tricks, but they usually involve more than a mere Ctrl-F5.
Without changing the HTML of the page I would say it's impossible.
For instance, you can add some "special" tags to the page header to disable browsers cache:
Is it really out of the question to do it server-side?
