Unixy Varnish v1.4.5 RC7 Released fixes Varnish Cache Error 400 Bad Requests

WHM/Cpanel and Direct Admin users who have installed Unixy Varnish Cpanel plugin would be happy to know Unixy Varnish v1.4.5 RC7 has been released to fix Varnish Error 400 Bad Requests error messages.

Google search for the error message shows various reasons for 400 Bad Requests errors related to backend Apache web server settings for LimitRequestFieldSize and LimitRequestLine. On the other end, it can also be caused by the Varnish Cache server’s own http request and response header length settings which were added in Varnish v3.x and default to 4096 bytes respectively which is half the size of Apache corresponding settings.

Unixy Varnish v1.4.5 RC7 release raised these limits for http request and response header length settings by 5x and 8x times their own pre-1.4.5rc7 defaults (which were 1/2 and 1/8th the size of the usual non-Unixy Varnish defaults).
