Layered page caching, warming and deployment consistency

With Shane Rounce

I teach layered page caching, warming and deployment consistency through a practical project, worked examples and checks that another person can repeat. This is a complete course plan; lesson recordings, workbooks and delivery are still to be produced.

4 weeks20 learning hoursSelf-paced

I’m developing this course as part of Learn Courses. This is the full teaching plan, ready to review before I produce the lessons and open enrolment.

IS THIS FOR YOU?

Who I’m building this for

Developers responsible for public-site performance.

Before you begin

A computer with a current browser and permission to use the project material.
Basic familiarity with Git and the relevant development tools. Work takes place in an isolated test environment.
No client records, credentials or production changes are needed for the exercises.

PROPOSED COURSE FEE

£149

Provisional planning figure, not an approved price or an offer for sale. I have assumed reusable self-paced lessons and bounded support. Production effort, access period, assessment support and tax treatment need confirming before sale.

Planning price only. Enrolment is closed and no payment is taken.

A PRACTICAL NEXT STEP

What you’ll be able to do

Trace origin, Redis, Varnish and edge responses with measurable hit and miss evidence.
Include block assets, headers and variants alongside cached markup.
Build a bounded warming list matching real public variants and exclusions.
Change a fixture and test cold, warm, purged and upstream-failure journeys.

THE TEACHING PLAN

Your next 4 weeks

A clear route through the subject, with something to make, test or reflect on at every stage.

MODULE 1

Map every cache layer

I explain the decisions behind map every cache layer using worked examples, a deliberately broken case and a corrected version. The lesson distinguishes what the evidence establishes from what still needs checking.

Your practical activity: Trace origin, Redis, Varnish and edge responses with measurable hit and miss evidence.
How I’ll check your understanding: Submit the working artefact and a short evidence note for module 1: trace origin, Redis, Varnish and edge responses with measurable hit and miss evidence. Include the initial state, the chosen change, a meaningful failure case and the result of the check. I review whether the evidence supports the conclusion and return specific revisions where it does not.

MODULE 2

Preserve response dependencies

I explain the decisions behind preserve response dependencies using worked examples, a deliberately broken case and a corrected version. The lesson distinguishes what the evidence establishes from what still needs checking.

Your practical activity: Include block assets, headers and variants alongside cached markup.
How I’ll check your understanding: Submit the working artefact and a short evidence note for module 2: include block assets, headers and variants alongside cached markup. Include the initial state, the chosen change, a meaningful failure case and the result of the check. I review whether the evidence supports the conclusion and return specific revisions where it does not.

MODULE 3

Coordinate purge and warming

I explain the decisions behind coordinate purge and warming using worked examples, a deliberately broken case and a corrected version. The lesson distinguishes what the evidence establishes from what still needs checking.

Your practical activity: Build a bounded warming list matching real public variants and exclusions.
How I’ll check your understanding: Submit the working artefact and a short evidence note for module 3: build a bounded warming list matching real public variants and exclusions. Include the initial state, the chosen change, a meaningful failure case and the result of the check. I review whether the evidence supports the conclusion and return specific revisions where it does not.

MODULE 4

Prove consistency under change

I explain the decisions behind prove consistency under change using worked examples, a deliberately broken case and a corrected version. The lesson distinguishes what the evidence establishes from what still needs checking.

Your practical activity: Change a fixture and test cold, warm, purged and upstream-failure journeys.
How I’ll check your understanding: Submit the working artefact and a short evidence note for module 4: change a fixture and test cold, warm, purged and upstream-failure journeys. Include the initial state, the chosen change, a meaningful failure case and the result of the check. I review whether the evidence supports the conclusion and return specific revisions where it does not.

PUT IT INTO PRACTICE

Your final project

Build and document a complete practical project for layered page caching, warming and deployment consistency. Use an invented organisation or an expressly permitted personal project, join the four module artefacts into one coherent result and demonstrate a normal journey, a failure state and a recovery or revision.

What you’ll produce

Module 1 artefact: Trace origin, Redis, Varnish and edge responses with measurable hit and miss evidence.
Module 2 artefact: Include block assets, headers and variants alongside cached markup.
Module 3 artefact: Build a bounded warming list matching real public variants and exclusions.
Module 4 artefact: Change a fixture and test cold, warm, purged and upstream-failure journeys.
A concise project brief, source and rights record, evidence log and handover with known limitations.

What good work looks like

Map every cache layer: 20 marks for a correct artefact, justified decisions and repeatable evidence.
Preserve response dependencies: 20 marks for a correct artefact, justified decisions and repeatable evidence.
Coordinate purge and warming: 20 marks for a correct artefact, justified decisions and repeatable evidence.
Prove consistency under change: 20 marks for a correct artefact, justified decisions and repeatable evidence.
Integration and handover: 20 marks for a coherent project, source acknowledgement, appropriate access and a clear explanation of remaining limits. Pass requires at least 70/100 and correction of any privacy, access or destructive-operation defect before completion.

Resources for your learning

A worked example and a deliberately broken fixture for map every cache layer.
A worked example and a deliberately broken fixture for preserve response dependencies.
A worked example and a deliberately broken fixture for coordinate purge and warming.
A worked example and a deliberately broken fixture for prove consistency under change.
A layered page caching, warming and deployment consistency workbook with evidence prompts and the capstone marking sheet.
A transcript, caption file and text-first lesson version for every recording.
A downloadable source-and-rights checklist and a sample completed project handover.

A course you can access

Provide edited captions, transcripts and a text-first route through every lesson.
Use keyboard-operable exercises, visible focus, legible contrast and no essential autoplay or motion.
Supply downloadable instructions and low-bandwidth alternatives; avoid timed assessment as a default.
Offer equivalent written evidence where live attendance or spoken presentation is a barrier and document support before enrolment.

FINISH WITH SOMETHING USEFUL

How you’ll complete the course

Submit all four module artefacts and respond to assessment feedback.
Complete the capstone at 70/100 or above with no unresolved access, privacy or destructive-operation defect.
Explain a meaningful failure case and the limits of the result in the evidence log.
Completion records describe assessed participation; I am not claiming external accreditation.

Completion will describe the work you have done. No external accreditation or professional qualification is claimed.

BEFORE I OPEN ENROLMENT

What I still need to finish

I’ll turn this plan into a delivered course once the teaching material and the learning service are ready.

Produce and editorially review the four lessons, worked examples, broken fixtures and marking guidance for layered page caching, warming and deployment consistency.
Build and test the course-specific workbook and capstone reference project using synthetic or permitted material.
Pilot the complete learner journey, including mobile, keyboard, captions, assessment feedback and recovery from interrupted access.
Approve the actual price, tax treatment, refund terms, access period, support boundaries and any cohort dates before accepting payment.
Implement and test authentication, server-side paid entitlements, webhook reconciliation, private asset access and tenant isolation before unlocking paid lessons.
Confirm tutor availability, feedback turnaround, moderation responsibilities and capacity before advertising tutor-led support.
Review source licences, sample rights and current official technical guidance before recording or publishing the material.

The ideas behind the course

My published articles are background reading for this plan. The full lessons, activities and assessment material still need producing.
