Hi,
I have an apache reverse proxy. I was using SetOutputFilter but I want to move to mod_filter.
Thus I declare a filter for proxy-html in the <VirtualHost> :
| Code: |
FilterDeclare proxyhtml
FilterProvider proxyhtml proxy-html "%{CONTENT_TYPE} =~ m|^text/html|"
FilterChain +proxyhtml
|
So far so good. But for one of my site (grafana), proxy-html "corrects" the pages and remove some parts of the code then grafana fails. Thus I want for this site to remove the filter (but only for this site).
I tried :
| Code: |
<Location "/grafana/">
FilterChain -proxyhtml
</Location>
|
but it doesn't work.
But if I do a :
| Code: |
<Location "/grafana/">
FilterChain !
</Location>
|
it works ! What am I doing wrong ? |

I can't explain why you can remove the entire filter chain, but not one filter. As an alternative, your could try putting the /grafana/ qualifier in your FilterProvider expression, viz.
| Code: | FilterDeclare proxyhtml
FilterProvider proxyhtml proxy-html "%{CONTENT_TYPE} =~ m|^text/html| && %{REQUEST_URI} !~ m|^/grafana/|"
FilterChain +proxyhtml |
