Bug Description

Binary package hint: lighttpd

Hi,
I am using 1.4.18-1ubuntu1.4 on Ubuntu Gutsy with security updates. I enabled mod_ssi using command "lighty-enable-mod ssi" and created a page with a few "include" directives.

Then, I displayed the page on "firefox", but no include directive was executed. When loading the same page with "wget" everything was correctly included.

I found that firefox was negotiating a compressed HTTP transport, while wget was using plain HTTP/1.0. So I tought that something could be wrong on compressed transfers.

Once removed "mod_compress" from lighttpd.conf, the server started to provide the correct page to all clients types.

So, probably, when using compression, mod_ssi is disabled.

Bye,
Giuseppe

I recently installed lighttpd and had the same problem. I found this bug report while searching for a solution. I thought I'd play with the order of loading modules and found that if mod_ssi is loaded in the lighttpd.conf server.modules section before mod_compress, then ssi and compression will both work. Apparently if done the other way around lighttpd compresses the file before it does the includes.

server.modules = (
            "mod_access",
            "mod_alias",
            "mod_accesslog",
# load mod_ssi before mod_compress or ssi won't work.
            "mod_ssi",
            "mod_compress",
# "mod_rewrite",
# "mod_redirect",
# "mod_status",
# "mod_evhost",
# "mod_usertrack",
# "mod_rrdtool",
# "mod_webdav",
# "mod_expire",
# "mod_flv_streaming",
# "mod_evasive"

lsw solution (with module loading reordering) helped me

This is still broken in Ubuntu 11.04. I'm observing this bug with lighttpd 1.4.28-2ubuntu1.

Still broken in Ubuntu 13.04.

lighttpd 1.4.42 includes mod_deflate, which can compress dynamically generated content, including that generated by mod_ssi. mod_deflate runs after the response has been prepared, as opposed to mod_compress, which (due to historic implementation) runs before the handlers/generators.
