Hello Alan and Leif, 

Thank you for your insight. 

I have downloaded and installed the header_filter plugin. However, I am having some difficulty with making it work. I can visit YouTube and other pages, but it seems to be ignoring the header manipulation. If you see any glaring mistakes, I would appreciate and advise you may have.

So far, I have the following configuration items:

--- records.config ---
CONFIG proxy.config.url_remap.remap_required INT 0

--- remap.config ---
regex_map http://www.youtube.com http://www.youtube.com @plugin=/libexec/trafficserver/header_filter.so @pparam=/etc/trafficserver/youtube.config
regex_map http://(.*) http://$1

--- youtube.config ---
X-YouTube-Edu-Filter +youtube_code_here+

I think it would be a good start, but the problem would be that he wanted this in a forward proxy. He would have to set up remap rules to trigger the header filtering only on the appropriate targets. I'm not sure if it would be simpler to tweak the plugin to check the URL or not.

Yeah. He could (as you said) create one (or a few) remap.config rules for youtube (he has to make sure remap.config is not required, but enabled via the reverse proxy config). E.g.

  map http://static.youtube.com  http://static.youtube.com @plugin=header_filter.so @pparam=youtube.config

or some such. Also remember he could use regular expressions here (on the host part). e.g.

  regex_map http://(.+)\.youtube\.(.+)  http://$1.youtube.$2 @plugin=header_filter.so

(or some such, I don't know what the various youtube URLs looks like).
