some links that helped me fiddle with iframe elements

Posted by jpluimers on 2019/01/16

I need to document this properly later, but here are some links I used when fiddling with iframe elements:

A few things I learned:

  • You can either put the iframe elements in different divs then arrange the divs, or put a different ID on each iframe and arrange the iframe. In either case you will need a float: left; in your style and a width: 100vw in the div around all your frames.
  • Be aware that 100% isn’t 100% out of the box: default browser styles have a margin around your page and a border around an iframe.
    So you will need to fiddle with margin and border-width inside your styles for body and iframe. Easiest is to set them to none or 0.
  • Viewport width/height works easier for me than raw %.
  • For one-off situations, I like the good old meta refresh over fiddling with JavaScript.

UptimeRobot is written in PHP and runs on IIS

Posted by jpluimers on 2018/11/28

In [WayBackJeroen Pluimers‏ @jpluimers: Every now and then editing @uptimerobot entries failed. Just “HTTP Error 503.4 – Service Unavailable The FastCGI pool queue is full” 1/2 I found out that UptimeRobot:

There is also a maintenance page at uptimerobot.com/maintenance.php#tvMode [Archive.is] and uptimerobot.com/maintenance.php?c-e [Archive.is]. If you get to those, then retry in ~10 minutes as sometimes it takes that long for an update to be processed.

Sometimes setting up multiple Android devices for the same uptimerobot account can be a bit of a hassle: [WayBack] Uptime Robot on Twitter: “Once logged in to the account from another Andriod device, that device will be added as an alert contact too.… “.

All in all it is still a nice tool (:

Load testing a web server on Windows using the ApacheBench benchmark tool from Apache

Posted by jpluimers on 2018/11/08

Based on:

  1. Download the most recent x64 Apache binaries for Windows from [WayBackApache VC15 binaries and modules download (at the time of writing: https://www.apachelounge.com/download/VC15/binaries/httpd-2.4.34-win64-VC15.zip )
  2. Extract recursively to D:\bin
  3. Run the UltrawareController locally
  4. Run D:\bin\httpd-2.4.34-win64-VC15\Apache24\bin\ab.exe -n 1000 -c 10 http://localhost:8000/foo

This will run the ab Apache benchmark tool with 1000 connections using 10 threads all doing the same http GET request at http://localhost:8000/foo

If you want to test TLS (https) connections, then you need to use the abs tool in the same directory as the ab tool supports http-only (when you still try, you get the message SSL not compiled in; no https support as explained in [WayBack] Add https support to Apache Bench on Windows – Stack Overflow).

Download location via [WayBack] windows – Is there any link to download ab Apache benchmark – Stack Overflow:

There are many more command-line parameters documented at [WayBack] ab – Apache HTTP server benchmarking tool – Apache HTTP Server Version 2.4, this is the summary:

Synopsis

ab [ -A auth-username:password ] [ -b windowsize ] [ -B local-address ] [ -c concurrency ] [ -Ccookie-name=value ] [ -d ] [ -e csv-file ] [ -f protocol ] [ -g gnuplot-file ] [ -h ] [ -Hcustom-header ] [ -i ] [ -k ] [ -l ] [ -m HTTP-method ] [ -n requests ] [ -p POST-file ] [ -Pproxy-auth-username:password ] [ -q ] [ -r ] [ -s timeout ] [ -S ] [ -t timelimit ] [ -Tcontent-type ] [ -u PUT-file ] [ -v verbosity] [ -V ] [ -w ] [ -x <table>-attributes ] [ -Xproxy[:port] ] [ -y <tr>-attributes ] [ -z <td>-attributes ] [ -Z ciphersuite ] [http[s]://]hostname[:port]/path

Posted by jpluimers on 2018/08/22

A great 404-page: [WayBackMarvin the Paranoid Android moans about requests for missing pages.

The fun about the WayBack link is that it fills the first memo field it finds (:
