#1803: Varnishncsa truncated referer

 I have a question concerning varnish and varnishncsa.

 In fact I've set up varnishncsa to log requests with this log format :


 {{{
  LOG_FORMAT="%{X-Forwarded-For}i %l %u %t \"%r\" %s %b \"%{Referer}i\"
 \"%{User-agent}i\""
 }}}



 But for long **refers**, I noticed that they are truncated, and when
 checked they are all limited to **247** characters.

 I've googled for a long time to figure out what can be the problem, but I
 didn't find a right answer.
 Do someone have ever have the issue, and can someone tell me how
 varnishncsa works in depth, and this issue can be solved
 please?Varnishncsa truncated referer

 Not all the log entry is truncated, but only the referer field.

 By looking the varnishncsa source code I noticed the function parse_format
 uses a static buffer of **256** octets. Is there where the size limit is
 set?

 Thank in advance for your help.
