The information in this article is provided as-is and to be used at own discretion. Depending on tool(s) used, customization(s), and/or other factors ongoing support on the solution below may not be provided by Qlik Support.
The default setting will still be a header size of 8192 bytes. The fix adds support for a configurable MaxHttpHeaderSize.
Steps:
[globals]
LogPath="${ALLUSERSPROFILE}\Qlik\Sense\Log"
MigrationPort=4545
