    # Override the mod_pagespeed 'rewrite level'. The default level
    # "CoreFilters" uses a set of rewrite filters that are generally
    # safe for most web pages. Most sites should not need to change
    # this value and can instead fine-tune the configuration using the
    # ModPagespeedDisableFilters and ModPagespeedEnableFilters
    # directives, below. Valid values for ModPagespeedRewriteLevel are
    # PassThrough, CoreFilters and TestingCoreFilters.
    #
    # ModPagespeedRewriteLevel PassThrough

    # Explicitly disables specific filters. This is useful in
    # conjuction with ModPagespeedRewriteLevel. For instance, if one
    # of the filters in the CoreFilters needs to be disabled for a
    # site, that filter can be added to
    # ModPagespeedDisableFilters. This directive contains a
    # comma-separated list of filter names, and can be repeated.
    #
    # ModPagespeedDisableFilters rewrite_images

    # Explicitly enables specific filters. This is useful in
    # conjuction with ModPagespeedRewriteLevel. For instance, filters
    # not included in the CoreFilters may be enabled using this
    # directive. This directive contains a comma-separated list of
    # filter names, and can be repeated.
    #
    # ModPagespeedEnableFilters rewrite_javascript,rewrite_css
    # ModPagespeedEnableFilters collapse_whitespace,elide_attributes

    # Explicitly forbids the enabling of specific filters using either query
    # parameters or request headers. This is useful, for example, when we do
    # not want the filter to run for performance or security reasons. This
    # directive contains a comma-separated list of filter names, and can be
    # repeated.
    #
    # ModPagespeedForbidFilters rewrite_images

    # How long mod_pagespeed will wait to return an optimized resource
    # (per flush window) on first request before giving up and returning the
    # original (unoptimized) resource. After this deadline is exceeded the
    # original resource is returned and the optimization is pushed to the
    # background to be completed for future requests. Increasing this value will
    # increase page latency, but might reduce load time (for instance on a
    # bandwidth-constrained link where it's worth waiting for image
    # compression to complete). If the value is less than or equal to zero
    # mod_pagespeed will wait indefinitely for the rewrite to complete before
    # returning.
    #
    # ModPagespeedRewriteDeadlinePerFlushMs 10

    # ModPagespeedDomain
    # authorizes rewriting of JS, CSS, and Image files found in this
    # domain. By default only resources with the same origin as the
    # HTML file are rewritten. For example:
    #
    #   ModPagespeedDomain cdn.myhost.com
    #
    # This will allow resources found on http://cdn.myhost.com to be
    # rewritten in addition to those in the same domain as the HTML.
    #
    # Other domain-related directives (like ModPagespeedMapRewriteDomain
    # and ModPagespeedMapOriginDomain) can also authorize domains.
    #
    # Wildcards (* and ?) are allowed in the domain specification. Be
    # careful when using them as if you rewrite domains that do not
    # send you traffic, then the site receiving the traffic will not
    # know how to serve the rewritten content.

    # You can also customize the number of threads per Apache process
    # mod_pagespeed will use to do resource optimization. Plain
    # "rewrite threads" are used to do short, latency-sensitive work,
    # while "expensive rewrite threads" are used for actual optimization
    # work that's more computationally expensive. If you live these unset,
    # or use values <= 0 the defaults will be used, which is 1 for both
    # values when using non-threaded MPMs (e.g. prefork) and 4 for both
    # on threaded MPMs (e.g. worker and event). These settings can only
    # be changed globally, and not per virtual host.

    # Randomly drop rewrites (*) to increase the chance of optimizing
    # frequently fetched resources and decrease the chance of optimizing
    # infrequently fetched resources. This can reduce CPU load. The default
    # value of this parameter is 0 (no drops).  90 means that a resourced
    # fetched once has a 10% probability of being optimized while a resource
    # that is fetched 50 times has a 99.65% probability of being optimized.

    # Many filters modify the URLs of resources in HTML files. This is typically

    # Certain common JavaScript libraries are available from Google, which acts

    #
    # ModPagespeedEnableFilters canonicalize_javascript_libraries

    # The following line configures a library that is recognized by
    # canonicalize_javascript_libraries.  This will have no effect unless you
    # enable this filter (generally by uncommenting the last line in the
    # previous stanza).  The format is:
    #    ModPagespeedLibrary bytes md5 canonical_url
    # Where bytes and md5 are with respect to the *minified* JS; use
    # js_minify --print_size_and_hash to obtain this data.
    # Note that we can register multiple hashes for the same canonical url;
    # we do this if there are versions available that have already been minified
    # with more sophisticated tools.
    #
    # Additional library configuration can be found in
    # pagespeed_libraries.conf included in the distribution.  You should add
