# Website Load Time
The _Website Load Time_ action step measures the time taken to load a website and the websites that it references. Referenced websites are websites that are embedded within a website and loaded automatically at the same time, e.g. visitor counters, analysis pages, Web stores, integrated payment systems, etc.
The _Website Load Time_ action step logs all data measured in a special file, identified by a `.har` extension (har = Http ARchive). This file is located in Windows under "My Documents → NameOfRPABuilderProject → Robot → trace → http@www-website-xx.har“. The name of the `.har` file is derived from the website tested (e.g. http@www-wikipedia-de.har). The file is overwritten every time the _Workflow_ is executed.
You can display the `.har` file using a suitable viewer. The viewer will show the load times of all website components in a waterfall diagram. There are many free viewers for `.har` files. The following list is not comprehensive:
  * http://www.softwareishard.com/har/viewer/
  * http://phantomjs.org/network-monitoring.html
  * 

Show the content of the waterfall file using a viewer, e.g. _softwareishard_ , as described below:
  1. Open the `.har` file in an ASCII editor, e.g. Notepad++.
  2. Select all using `<CTRL>` + and copy the entire content of the file to the clipboard using `<CTRL>` + .
  3. Start the viewer, e.g. _softwareishard_ , in a browser.
  4. Paste the content of the clipboard into the input field on the website using `<CTRL>` + 
  5. Click the <Preview> button.
  6. The next page of _softwareishard_ , which is on the "Preview" tab, shows the waterfall diagram of your measurement. The components of the website of interest are shown on the left of the page and the load times are shown on the right.


Error message: FAIL to load the address. The error message "FAIL to load the address" will be recorded in the `.har` log file if the _Website Load Time_ action step was unable to load the specified URL.
It is also possible to perform further processing on the measured values for _Website Load Time_ using the _Website Load Time.Result_ variable. This variable has the same content as the `.har` file after the action step has been executed.
## Properties
**Load Time Settings**
  * **WebsiteUrl** Enter the URL to be tested, e.g. www.wikipedia.de.


Other Properties that are the same in all action steps in the _Web Automation_ are described in the section on **Common Properties**. For reasons of clarity they are not shown here.
## Inbound Variables
**WebsiteUrl** Enter the URL to be tested, e.g. www.wikipedia.de.
## Outbound Variables
**Result** The _Website Load Time.Result_ variable provides the results of the load time measurement in the form of a log (the log has the same content as the `.har` file).
**IsOnline** The _Website Load Time.IsOnline_ variable records whether the website tested was available or not (True/False).
## Wizard
  * **WebsiteUrl** Enter the URL to be tested, e.g. www.wikipedia.de. The URL can also be constructed by inserting variables from the _Workflow_.


Error message: FAIL to load the address. The error message "FAIL to load the address" will be recorded in the `.har` log file if the _Website Load Time_ action step was unable to load the specified URL.
