164 * GOTCHA #1: When sending the headers for caching, we must send Expires,
165 * Last-Modified, Pragma, and Cache-Control headers. If we don't PHP
3e6ee6ca 166 * will makeup values that will break the cacheing.
86921eda 167 *
168 * GOTCHA #2: If the current template does not contain a template named
169 * stylesheet.tpl, this cacheing will break because filemtime() won't
170 * work. This is a problem e.g. with the default_advanced template
171 * that inherits CSS properties from the default template but
172 * doesn't contain stylesheet.tpl itself.
3e6ee6ca 173IDEA: 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!)
94b68ceb 174 * Possibly naive suggestion - template can define its own default
175 * template name
86921eda 176 *
3e6ee6ca 177 * GOTCHA #3: If the user changes user prefs for things like font size then
178 * the mtime should be updated to the time of that change, and not
179 * that of the stylesheet.tpl file. IDEA: can this be a value kept
180 * in user prefs (always compare to actual file mtime before sending
181 * to the browser)
182 *
86921eda 183 * TODO: Fix this. :)
