151 | * GOTCHA #1: When sending the headers for caching, we must send Expires, |
152 | * Last-Modified, Pragma, and Cache-Control headers. If we don't PHP |
3e6ee6ca |
153 | * will makeup values that will break the cacheing. |
86921eda |
154 | * |
155 | * GOTCHA #2: If the current template does not contain a template named |
156 | * stylesheet.tpl, this cacheing will break because filemtime() won't |
157 | * work. This is a problem e.g. with the default_advanced template |
158 | * that inherits CSS properties from the default template but |
159 | * doesn't contain stylesheet.tpl itself. |
3e6ee6ca |
160 | IDEA: So ask the Template class object to return the mtime or better yet, the full file path (at least from SM_PATH) by using $oTemplate->get_template_file_path(stylesheet.tpl) but this is still a problem if the default template also does not have such a file (in which case, we fall back to SM's css/deafult css file (so in that case, go get that file's mtime!) |

161 | * Possibly naive suggestion - template can define its own default |
162 | * template name |
86921eda |
163 | * |
3e6ee6ca |
164 | * GOTCHA #3: If the user changes user prefs for things like font size then |
165 | * the mtime should be updated to the time of that change, and not |
166 | * that of the stylesheet.tpl file. IDEA: can this be a value kept |
167 | * in user prefs (always compare to actual file mtime before sending |
168 | * to the browser) |
169 | * |
f46db954 |
170 | * Comment re gotcha #3: If we only define basic font prefs here, we really |
171 | * only need to refresh the cache if one of the font prefs changes. |
172 | * Possibly some type of "force nocache flag could be set if a font pref is |
173 | * changed? |
10c46cec |
174 | * |
175 | * Response: Perhaps, if that can be implemented great, but I think the |
176 | * user prefs solution would definitely work: catch the font setting change |
177 | * in a custom save() routine from user prefs and away we go. |
178 | * |
