Component:  varnishd  |     Version:  2.0

 Varnish 2.0.3/2.0.4/2.0.5

 Apache2.2.14

 When using Varnish with esi includes, if the backend has mod_deflate
 enabled, the ESI include request appears to have the request sent through
 with Accept-Encoding: gzip,deflate (or whatever the browser requesting the
 page that contains the esi:include has sent)

 Temporarily disabling mod_deflate allows ESI to work correctly.  Setting
 -p esi_syntax=0x1 on the command line doesn't appear to work either.  If I
 leave mod_deflate on, and do the request manually without Accept-Encode,
 the ESI include works.

 I believe eliminating the Accept-Encoding header from the request when
 doing an ESI include would probably fix the issue.
