-
-Apache Traffic Server web content optimization plugin powered by Google PageSpeed
-
-http://www.atsspeed.com/
-
-To build, a simple 'make' should work. Use 'sudo make install' to install.
-Optionally, patching ATS with ethread.patch helps with eliminating latency that
-sometimes gets induced when synchronising ATS's and PSOL's thread pools.
-
-After that, update ATS's plugin.config with:
-```
-ats_speed.so
-gzip.so /usr/local/etc/trafficserver/gzip.config
-````
-gzip.so also is build with ats_speed, as it currently is a slightly
-modified version of the official one from the ATS repository.
-
-There are some hard-coded things in the plugin, these directories should exist:
-- /tmp/ps_log/ to exist
-- /tmp/ats_ps/ to exist
-
-Configuration files go into `/usr/local/etc/trafficserver/psol.`
-That folder is monitored, and changes to files in there are picked
-up immediately. A sample configuration:
-
-```
-# [host]
-[192.168.185.185]
-# Force traffic server to cache all origin responses
-override_expiry
-pagespeed FlushHtml on
-pagespeed RewriteLevel CoreFilters
-pagespeed EnableFilters rewrite_domains,trim_urls
-pagespeed MapRewriteDomain http://192.168.185.185 http://www.foo.com
-pagespeed MapOriginDomain http://192.168.185.185 http://www.foo.com
-pagespeed EnableFilters prioritize_critical_css,move_css_to_head,move_css_above_scripts
-pagespeed EnableFilters fallback_rewrite_css_urls,insert_img_dimensions,lazyload_images,local_storage_cache
-pagespeed EnableFilters prioritize_critical_css,rewrite_css
-pagespeed EnableFilters combine_javascript,combine_css
-```
-
-It also expects this in records.config from ATS to function:
-`CONFIG proxy.config.url_remap.pristine_host_hdr INT 0`
-
-You can view debug output of the plugin using `traffic_server -T ".*speed.*"`
-
-The current state compiles against PSOL 1.7.30.4-beta.
-Please note the this plugin will generate asserts when build against
-the debug version of mps (option->Merge from a different thread).
