SleekPixel for WP Super Cache configuration writeups
WP Super Cache from Automattic generates static HTML files and serves them via mod-rewrite or a PHP wrapper. The configuration writeups get a SleekPixel card with the active mode, the cache state, and a brand mark, drawn from safe configuration values.

Super Cache writeups need mode-shaped previews
WP Super Cache stores its configuration in the wp_super_cache_settings option and in a small set of constants written into wp-config.php. The serialized array carries the active caching mode (mod-rewrite, PHP, legacy), the expiry time, the compression toggle, the cache-rebuild flag, and the GC schedule. Cache files live in wp-content/cache/supercache/ as per-URL HTML snapshots. The configuration values are safe to expose at a summary level. The cache directory is operational and never belongs on a public share.
Setup writeups for WP Super Cache walk readers through picking the right mode, configuring expiry, and verifying the cache works. The audience is performance-aware site owners and engineers researching the right caching setup. The share preview is what they see first when a forum link or a Slack message lands. A generic homepage banner reads as marketing copy. A real mode card with the active mode badge, expiry label, and compression flag communicates the configuration directly in the preview.
SleekPixel binds to a setup-post type with fields for setup phase, summary, and the cache mode. A whitelisted subset of wp_super_cache_settings renders as small configuration badges. The render produces a 1200x630 PNG that surfaces the Super Cache posture for every share.
Workflow
From WP Super Cache config to setup card
Set up the writeup post type
Whitelist safe Super Cache fields
wp_super_cache_settings are safe to expose: active mode, expiry time, compression flag, GC schedule label. The cache directory and per-URL HTML snapshots stay outside the whitelist.
Bind template fields
Publish or update the post
Output
Sample WP Super Cache setup card
A 1200x630 OG card from a WP Super Cache writeup: active mode badge, expiry meta line, compression flag, brand mark, and a clean setup-phase label.
Comparison
Default theme OG vs SleekPixel for WP Super Cache
Default theme OG image
- Super Cache setup writeups share with the same banner as any marketing post
- Active mode (mod-rewrite, PHP, legacy) never appears in the social preview
- Expiry and compression state stay invisible to anyone forwarding the link
- Manual exports of mode diagrams stop happening after the first writeup
- Performance researchers see no concrete configuration signal before clicking

Features
What SleekPixel gives you for WP Super Cache
Mode-aware setup badges
The active WP Super Cache mode renders as a primary badge on the card: mod-rewrite, PHP, or legacy. The badge updates on every post save when the mode changes in the configuration, so the share always reflects the current setup.
Expiry-time labels
The configured cache expiry time renders as a small meta line on the card. Hours, days, or 'never' formats are supported as labels. Editors do not need to type the expiry manually because the value comes from the configuration.
Compression-state badges
When the gzip compression toggle is active, a small badge renders to communicate the compression state. The badge stops rendering when compression is disabled on subsequent post saves, so the share stays honest.
Use cases
Where WP Super Cache users benefit from mode shares
Configuration tutorials
How-to posts on picking the right WP Super Cache mode get a tutorial card with the recommended posture as a sample. The visual signals the technical nature before the click.
Mode migration writeups
Posts that document a move from PHP mode to mod-rewrite get a before-and-after mode card. The visual communicates the migration shape at a glance for performance-aware readers.
Agency client recaps
Agencies running Super Cache for client sites publish per-client setup recaps. The card carries the client brand and the mode posture for procurement-grade evidence.
The bigger picture
Why Super Cache writeups need mode-shaped shares
WP Super Cache is one of the longest-standing caching plugins for WordPress, maintained by Automattic. The setup writeups that document the right mode for a given hosting environment are reference material for site owners researching the right configuration. The share preview is what surfaces in forum threads and Slack channels when the writeup gets linked.
A generic homepage banner reads as a marketing post and gets ignored by readers looking for technical reference material. A mode-aware card with the active mode badge, the expiry label, and the compression flag reads as a real configuration document. The compounding effect is the discoverability of the writeup.
Posts that share well get more links, more forum mentions, and more inbound traffic from search. Posts that share poorly get fewer of all three. WP Super Cache provides the configuration through safe options.
SleekPixel takes those options, binds them through a whitelist, and renders the cards that turn the underlying caching configuration into visible mode-shaped evidence across every setup writeup.
Questions
Common questions about SleekPixel for WP Super Cache
No. The HTML snapshots live in wp-content/cache/supercache/ and are operational. SleekPixel only reads whitelisted configuration values from wp_super_cache_settings. The snapshot directory and per-URL files stay outside any template binding.
WP Super Cache exposes cache-hit counts in its admin pages but most teams prefer to keep those counts off public share cards. The 'mode active' and 'compression on' badges are the safe alternatives and communicate the posture without leaking volume.
Yes. The REST-cache mode is exposed through the same configuration options and can render as an additional badge through the whitelist if you choose to expose it. The badge reflects the actual REST-cache state and updates on every post save.
WP Super Cache includes a basic CDN URL rewrite. When the rewrite is active, a CDN-bridge badge can render through a whitelisted flag. The actual CDN delivery happens on the frontend and does not interact with the share render at all.
Yes. Initial setup and mode migration each use a writeup-type-specific template variant. Migration writeups can render a before-and-after mode card, while setup writeups render a single mode card. The selection is bound to the writeup-type field on the post.
No. The cache flush runs through WP Super Cache's hooks on post save. SleekPixel runs on the same save event but writes to uploads, not to the cache directory. The two operations are independent and do not contend for resources at any point.
Yes, as a small label drawn from a whitelisted summary of the garbage-collection schedule. The label renders as 'GC every N hours' or similar, depending on the configured schedule, alongside the other configuration meta.
All three WP Super Cache modes are supported as primary-badge labels: mod-rewrite, PHP, and legacy. The badge respects whichever mode is active in the configuration and updates on the next post save when the team migrates between modes.
