SSI silently fails with subs_filter

[GoogleCodeExporter]

What steps will reproduce the problem?
1. enable ssi
2. include ssi statement in html which works example : <!--# include fil
e="/filename.html" -->
3. include a subs_filter

What is the expected output? What do you see instead?

The expected output should be the strings substituted as per the subs_filter 
directives and ssi includes to also work.

Instead, the subs_filter works perfectly, but it is breaking ssi.

removing the subs_filter from nginx.conf makes ssi working again as expected.

What version of the product are you using? On what operating system?

in case it helps my subs filters looked like this

subs_filter_types text/html;
subs_filter 'http://some.host.com/somefile-3.js' 
'http://some.host.com/somefile-4.js';
subs_filter 'http://some.host.com/somefile-2.js' 
'http://some.host.com/somefile-4.js';
subs_filter 'http://another.host.com/somefile.js?v=12' 
'http://some.host.com/somefile-4.js';
subs_filter 'http://another.host.com/somefile.js?v=1' 
'http://some.host.com/somefile-4.js';
subs_filter 'http://some.host.com/somefile.js' 
'http://some.host.com/somefile-4.js';

Do you mean the strings which need to be replaced are produced by SSI module?

It's difficult to do that because the SSI filter module processes the body 
content after my substitutions filter module. substitutions module can't 
replace the content which has not produced. These filter module has specific 
order in Nginx.

Also the native Nginx substitution module can't do that. Sorry.

hi Yaoweibin,

No, I am not looking to substitute the output produced from SSI module.

Just that when I am using subs_filter, the SSI module does not work at all.

It acts as if it were dissabled.
