https://wordpress.org/support/topic/all-website-pages-downloading-gz-file-after-latest-update?replies=28#post-7494087

2015-09-24 10:39 donncha
* wp-cache-phase2.php: Reduce "needs rebuild" time to 10 seconds,
so those pages refresh faster.
2015-08-28 16:28 donncha
* wp-cache-phase1.php: Because sometimes your editing in HTTPS
while your site is on HTTP. Thanks kraftbj
2015-08-25 21:42 kraftbj
* wp-cache-phase2.php: Swap post_permalink with get_permalink. Both
are exactly the same and old enough to not impact any users.
post_permalink slated for deprecation in 4.4.
2015-08-10 14:06 donncha
* wp-cache-phase2.php: Avoid PHP warnings, props @daneodekirk
2015-08-10 13:25 donncha

* Changelog.txt, readme.txt: Updated changelog
2015-07-29 13:08 donncha
* wp-cache-phase2.php: Remove this function call as it's not
defined. Ref:
https://github.com/Automattic/wp-super-cache/commit/4f3229009e5c6c8487dd883910ea076a8e3b7e26
2015-07-27 16:36 kraftbj
* wp-cache.php: Don't flush settings for expiry time and garbage
collection. See
https://github.com/Automattic/wp-super-cache/pull/49
2015-07-27 16:28 donncha
* wp-cache-base.php: Remove CacheMeta class as it's not used any
more and caused APC errors. Ref:
https://github.com/Automattic/wp-super-cache/pull/21
2015-07-24 15:21 kraftbj
* wp-cache.php: Check if listfile isset to prevent PHP warning.
2015-07-23 13:56 donncha

when submitting the easy settings form. Thanks Jeremy Herve for
the bug report!
2015-07-22 15:52 donncha
* Changelog.txt, readme.txt: Updated changelog
2015-07-22 11:25 donncha
* wp-cache-phase2.php: Fixed typo in debug log entry
2015-07-15 11:56 donncha
* wp-cache.php: * Added uninstall function as well as deactivate
function. The deactivate function does not delete the config file
but it does disable caching because scheduled jobs must be
enabled in the settings page when the config file is used on
activation again.
* Fixed a bug where deactivating the plugin without visiting the
settings page causes a fatal error so the plugin can't be
deactivated
2015-07-02 14:19 donncha
* wp-cache-phase2.php: Minor changes to debugging
2015-07-02 13:58 donncha

file to be deleted doesn't exist
* Add extra debugging
2015-07-02 12:10 donncha
* wp-cache-phase2.php: Remove https from the home url as well
2015-07-01 16:37 donncha
* wp-cache-phase2.php: As so many checks for "should we cache this
page?" were put to the end of page generation the rebuild system
was broken. This fixes it by deleting the rebuild files created
earlier if the current page isn't to be cached (and thus creating
new cache files)
2015-07-01 15:46 donncha
* wp-cache-phase1.php: Always make sure supercachedirs have
trailing slashes
2015-07-01 15:30 donncha

wp_cache_get_cookies_values() for repeat calls

* plugins/domain-mapping.php: Suercache urls end in slashes
2015-06-23 15:32 kraftbj
* wp-cache-phase1.php: Check for If-Modified-Since before using it
as it is not always defined.
2015-06-03 02:36 kraftbj
* advanced-cache.php: Do not display broken messages for XMLRPC,
REST, AJAX requests.
2015-05-15 14:12 kraftbj
* wp-cache-phase2.php, wp-cache.php: Fix improper site_url usage
* Update site_url to home_url in another e-mail subject
* Use admin_url instead of constructing URL from site_url
2015-05-15 14:08 kraftbj
* wp-cache.php: Use home_url in Preload Cron e-mails.
2015-05-15 11:13 donncha

not needed any more.

positives.

2015-04-29 15:45 donncha

Likewise, preload as many posts as you can and enable "Preload Mode". Garbage collection will still occur but it won't affect the preloaded files. If you don't care about sidebar widgets updating often set the preload interval to 2880 minutes (2 days) so all your posts aren't recached very often. When the preload occurs the cache files for the post being refreshed is deleted and then regenerated. Afterwards a garbage collection of all old files is performed to clean out stale cache files.
With preloading on cached files will still be deleted when posts are made or edited or comments made.

WP Super Cache 1.4 introduced a cacheaction filter called wpsc_cachedata. The cached page to be displayed goes through this filter and allows modification of the page. If the page contains a placeholder tag the filter can be used to replace that tag with your dynamically generated html.
The function that hooks on to the wpsc_cachedata filter should be put in a file in the WP Super Cache plugins folder unless you use the late_init feature. An example plugin is included. Edit [dynamic-cache-test.php](http://svn.wp-plugins.org/wp-super-cache/trunk/plugins/dynamic-cache-test.php) to see the example code.
There are two example functions there. There's a simple function that replaces a string (or tag) you define when the cached page is served. The other example function uses an output buffer to generate the dynamic content. Due to a limitation in how PHP works the output buffer code MUST run before the wpsc_cachedata filter is hit, at least for when a page is cached. It doesn't matter when serving cached pages. See [this post](http://ocaoimh.ie/y/6j) for a more technical and longer explanation.
