I will provide a comprehensive solution for image processing and fallback mechanisms. I will use ImageMagick to convert images to various sizes and ensure that both .webp and .jpg formats are available. The images will be organized in Google Cloud Storage with a clear naming convention, facilitating efficient retrieval.
For content negotiation, I will configure the server to examine the Accept header for image/webp support. If supported, .webp versions will be served; otherwise, requests will be rewritten to .jpg format.
I will set up Google Cloud CDN to point to the storage bucket and configure caching rules for both image versions. Additionally, URL rewriting rules will be implemented to serve the correct format based on browser support.
Extensive testing across various browsers will ensure the correct image format is delivered, with a seamless fallback to .jpg when .webp is unsupported. Monitoring and logging will be enabled to assess CDN performance and verify the effectiveness of the fallback mechanism.
The deliverables will include ImageMagick scripts, server-side configurations, CDN setup, and detailed documentation on naming conventions and storage structure. A test report will showcase successful content negotiation and image delivery across browsers, along with monitoring setup and log interpretation instructions.
