| ATS (Apache Traffic Server) Inliner plug-in |
| ----------------------------------------------- |
| |
| This is a global transformation plug-in that inlines base64 images on text/html responses. |
| |
| Inliner: |
| 1. Detects the response to have header "Content-Type" set to "text/html". |
| 2. Without impacting streaming, scans the mark-up looking for "src" attributes |
| into "img" tags. |
| 3. For each detected http/https url, checks for a "#inline" at its end. |
| 4. Checks on ATS cache if the url exists. |
| 5. In case the url exists into the cache. Inliner replaces the image with a 1x1 |
| base64 pixel and starts retrieving the content from the cache. |
| 6. Once the image is retrieved, buffers its content into memory. |
| 7. At the end of the original document, Inliner outputs a little JavaScript |
| snippet. |
| 8. Inliner outputs every image found into the cache into a JavaScript function |
| call. |
| 9. Once the JavaScript gets executed by the browser, the 1x1 pixels |
| are replaced by their actual content. |
| 10. For the images which do not exist into the cache, Inliner preserve their |
| original url and retrieves their content into background, also converting |
| them to their base64 representation. |
| |
| Please use "inliner" tag for debugging purposes. |
| |
| Please add the inliner library into ATS plugins.conf configuration file. |
| |
| No special configurations are required |
