Re: [squid-users] Did Anyone used ESI with squid ?

Dear Nitesh,

It looks like the header is ok, since ESI processing started. I also had
  problems with parser 'libxml2' - it was constantly reporting some
parsing errors even on simple pages which were validated with W3C validator.

So finally I changed to 'custom' and 'expat' parsers.

I suggest you first try some really simple ESI constructs with 'custom'
parser.

Regards,
Michal
