User-agent string used in HTTP tests is changing

by / Monday, 29 July 2013 / Published in Status Updates

An HTTP test at AlertFox involves more than simply pinging port 80 (or  443). Instead, our test servers initiate a real HTTP connection. That’s why we are able to check for keywords on the served page.

It has now come to our attention that the user-agent used by our HTTP test may cause servers to respond with a 404 although they are actually up and running.

In order to overcome this issue, we will slightly adjust the user-agent for the HTTP tests to state

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)

We took out “myIE2”, which represents the Maxthon browser. Some sites seem to block responses based on this string. The change will take place tomorrow, Tuesday, July 30, 2013.
