General un-handled exception occurred during socket I/O read
from web-server '%1' retrieving URI '%2'. Explanation message: '%3'.
Explanation
This error occurs when the server abruptly closes
the connection to the virtual user. Servers might close connections
if the virtual user is detected as a security risk due to a invalid
cookie, failed SSL negotiation, or an improperly formatted request.
System action
The request is skipped.
User response
Compare the request that was sent at run time (in
the test log) to the one that is in the test. To determine if differences
between the requests are valid, record the test again and compare
the two requests.
