How to warm-up SharePoint or other web applications and WCF (SOAP) services with PowerShell

There are many reasons you might want to warm-up a web application occasionally. It can be after a fresh deployment or on a regular basis after recycling application pools. Some times you might also need to warm-up SOAP services without going through front-end.

It might seems to be any easy task specially if you have PowerShell 3.0 or higher on your servers, but after Googling a while and reviewing some of the top hits I discovered that each solution is missing a part. Some only work in a single server scenario and some has forgotten that each HTTP response might contain links to scripts and images that we need to download and finally I could not find anything for SOAP services that just works. Long story short I decided to put together a simple script that just works and is easy to change to everyone’s needs.

Please note that my only assumption is you have PowerShell 3.0+ in your servers.

Currently the script takes care of the following tasks, but I will most likely improve it to cover other useful scenarios.

  • Calling SOAP operations and sending parameters and custom headers
  • Calling front-end URIs and downloading scripts and images that are local to the front-end
  • Logging to a configurable folder and file name
  • Cleaning up old log files

Currently, I have the following points in mind to improve the script.

  • Put configuration in a different file.
  • Improve function definitions (named and typed parameters and description).
  • Default values for parameters when it makes sense (e.g. log folder can be the current folder).
  • Support REST services.

I’m open to any suggestion and feature request. Please let me know if you found it useful or if have got something wrong.
