What is IOException in the ServoyFilter.doGet?

[antonio]

A few times each day I get this error in the servoy log. Can anyone give me some pointers on where to start looking for its cause? This is Servoy 5.2.12 running on Windows Server 2008 R2

Code: Select all

this can be ignored i think, what happens here is that the browser kills a ongoing request to the server.
For example a user closes the browser when a request is in progress, or a user goes to another page when a request is in progress, and the browser just terminates the connection at his end

Still happens with Version 7.4.1

[jcompagner]

yes and nothing we can really do about
as i said the browser has terminated the connection when a response is being send from server to the browser.
