phpapache.htaccessmod-deflate

Can I tell mod_deflate & PHP to skip compression on one directory only?

To compress all my web page, I use this .htaccess code. It uses Apache deflate module if possible, else apply the PHP ob_gzhandler compression.

Everything is working fine, but for specific reason, I don't want to apply the compression for the folder ./folderWithoutCompression.

Question : How can I add this exception in case of Apache deflate module is defined or not (PHP ob_gzhandler case) in my following script below?

<IfModule mod_deflate.c>
  # force deflate for mangled headers
  # developer.yahoo.com/blogs/ydn/posts/2010/12/pushing-beyond-gzipping/
  <IfModule mod_setenvif.c>
    <IfModule mod_headers.c>
      SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15}|~{15}|-{15})$ ^((gzip|deflate)\s*,?\s*)+|[X~-]{4,13}$ HAVE_Accept-Encoding
      RequestHeader append Accept-Encoding "gzip,deflate" env=HAVE_Accept-Encoding
    </IfModule>
  </IfModule>

  # HTML, TXT, CSS, JavaScript, JSON, XML, HTC:
  <IfModule filter_module>
    FilterDeclare   COMPRESS

    FilterChain     COMPRESS

  </IfModule>

  <IfModule !mod_filter.c>
    # Legacy versions of Apache

    AddOutputFilterByType DEFLATE image/svg+xml application/vnd.ms-fontobject 
    AddOutputFilterByType DEFLATE application/x-font-ttf font/opentype
  </IfModule>
</IfModule>

<IfModule !mod_deflate.c>
    #Apache deflate module is not defined, active the page compression through PHP ob_gzhandler
    php_flag output_buffering On
    php_value output_handler ob_gzhandler
</IfModule>

EDIT

As workaround, I am using a custom content-type for all files present in my folderWithoutCompression folder.

I am sure that it is possible to exclude some directory using <Location>, <LocationMatch>, <DirectoryMatch> or <Directory>, but when I try to deal with, I always got an Apache error 500

Solution

    Thanks @Gumbo

    # for URL paths that begin with "/foo/bar/"
SetEnvIf Request_URI ^/foo/bar/ no-gzip=1

# for files that end with ".py"
<FilesMatch \.py$>
    SetEnv no-gzip 1
</FilesMatch>
