| 196 This page tells you how to host <code>.crx</code> files | |
| 197 on your own server. | |
| 198 If you distribute your extension, app, or theme solely through the | |
| 199 <a href="http://chrome.google.com/webstore">Chrome Web Store</a>, | |
| 200 you don't need this page. | |
| 201 Instead, consult the | |
| 202 <a href="http://www.google.com/support/chrome_webstore/">store help</a> and | |
| 203 <a href="http://code.google.com/chrome/webstore/index.html">developer documentat
ion</a>. | |
| 204 </p> | |
| 205 <p> | |
| 206 By convention, extensions, | |
| 207 installable web apps, and themes are served—whether | |
| 208 by the Chrome Web Store or by a custom server—as | |
| 209 <code>.crx</code> files. | |
| 210 When you upload a ZIP file with the | |
| 211 <a href="https://chrome.google.com/webstore/developer/dashboard">Chrome Develope
r Dashboard</a>, | |
| 212 the dashboard creates the <code>.crx</code> file for you. | |
| 213 </p> | |
| 214 <p> | |
| 215 If you aren't publishing using the dashboard, | |
| 216 you need to create the <code>.crx</code> file yourself, | |
| 217 as described in <a href="packaging.html">Packaging</a>. | |
| 218 You can also specify | |
| 219 <a href="autoupdate.html">autoupdate</a> information to ensure that | |
| 220 your users will have the latest copy of the <code>.crx</code> file. | |
| 221 </p> | |
| 222 <p> | |
| 223 A server that hosts <code>.crx</code> files | |
| 224 must use appropriate HTTP headers, | |
| 225 so that users can install the file | |
| 226 by clicking a link to it. | |
| 227 </p> | |
| 228 <p> | |
| 229 Google Chrome considers a file to be installable | |
| 230 if <b>either</b> of the following is true: | |
| 231 </p> | |
| 232 <ul> | |
| 233 <li> | |
| 234 The file has the content type | |
| 235 <code>application/x-chrome-extension</code> | |
| 236 </li> | |
| 237 <li> | |
| 238 The file suffix is <code>.crx</code> | |
| 239 and <b>both</b> of the following are true: | |
| 240 <ul> | |
| 241 <li> | |
| 242 The file <b>is not</b> served with | |
| 243 the HTTP header <code>X-Content-Type-Options: nosniff</code> | |
| 244 </li> | |
| 245 <li> | |
| 246 The file <b>is</b> served | |
| 247 with one of the following content types: | |
| 248 <ul> | |
| 249 <li> empty string </li> | |
| 250 <li> "text/plain" </li> | |
| 251 <li> "application/octet-stream" </li> | |
| 252 <li> "unknown/unknown" </li> | |
| 253 <li> "application/unknown" </li> | |
| 254 <li> "*/*" </li> | |
| 255 </ul> | |
| 256 </li> | |
| 257 </ul> | |
| 258 </li> | |
| 259 </ul> | |
| 260 <p> | |
| 261 The most common reason for failing to recognize an installable file | |
| 262 is that the server sends the header | |
| 263 <code>X-Content-Type-Options: no sniff</code>. | |
| 264 The second most common reason | |
| 265 is that the server sends an unknown content type—one | |
| 266 that isn't in the previous list. | |
| 267 To fix an HTTP header issue, | |
| 268 either change the configuration of the server | |
| 269 or try hosting the <code>.crx</code> file at another server. | |
