description:
Sub filter: support of multiple strings to replace.

Hello,

Can you please provide an example of use.

Thank you!

See an example in the module documentation:
http://nginx.org/en/docs/http/ngx_http_sub_module.html

Thanks, I am aware of that.  What is missing from the docs is the
format for multiple sub_filter entries.

Is it:

a) sub_filter "matchA" "replaceA" "matchB" "replaceB";

b) sub_filter "matchA" "replaceA"
      sub_filter "matchB" "replaceB"

c) sub_fitler "match1" "match2" "match3" "replaceAll"

d) Only 1 sub_filter allowed per location or server
Only this option is applicable here.

And then there's the issue of sub_filter_last_modified and
sub_filter_once applying to all, or just the preceding or the
following entry?
sub_filter_once on; is designed to support configurations like this one:

    sub_filter '<head> '<head><link ...>';
    sub_filter '<body> '<body><script ...>';
        
Here, each replacement will be applied only once.


Multiple sub_filters is a great addition, docs are unclear on usage.  :-)
