Overview
Comment: | Reworked GetMimeType() to allow for type-specific flags such as eliding the charset from Content-Type (necessary for wasm). This also fixes the duplicate charset specifications which were previously being emitted for .html and .htm files. |

| ||
20:45 | Implemented handling of the MTF_NOCGI mimetype flag, currently used only by wasm files. ... (check-in: 1b62b4668c user: stephan tags: trunk) | |
20:15 | Reworked GetMimeType() to allow for type-specific flags such as eliding the charset from Content-Type (necessary for wasm). This also fixes the duplicate charset specifications which were previously being emitted for .html and .htm files. ... (check-in: 32df1a6170 user: stephan tags: trunk) | |
18:42 | Added .wasm ==> application/wasm mimetype mapping because it's needed for loading wasm files. ... (check-in: 16e8ae3e8f user: stephan tags: trunk) | |
