Will take a look thanks.

@oleacs I apologize for the delay. This ticket managed to get lost in the all the static.

I've attempted to replicate your issue as stated above, and also by changing the supplied request URL, with no luck.

I saw a slow response time due to the repeated test( ) HTTP requests chewing up ASIO. Can you provide any further information and I'll prioritise this ticket?
