about the response content-length with ESI page in the log

[姚伟斌]

Hello,

I don't know if it's a bug. We use the ESI page in our site. I saw the
varnishncsa.log was like this:

127.0.0.1 - - [29/Mar/2012:21:44:23 +0800] "GET

The main page includes an tiny subpage about 200bytes. The main page
is about 100k. In the ncsa log, It just displayed the subpage
content-length, not the main page length or the merged page length. It
confused me a little a the first glance.
