A set of error handlers that extends TYPO3's default site error handling (work in progress).
Shows content from a page or external URL.
If the resource is unavailable or the content is empty a message in the standard TYPO3 error layout is shown.
When the requested URL denotes a web resource (eg .css) only a small response is sent to save bandwidth ("Regular expression for resource file extensions", see Extension Manager Configuration).
The file extensions to be treated by default as web resources:
- css
- eot, ttf, woff, woff2
- gif, ico, jpg, jpeg, png, svg, webp
- js
- json
- xml
Redirects to a login URL if access to page without session is not permitted.
If the user is already logged in, but has no access because of missing group rights he will be optionally redirected to a fallback page ("Show Content from Page on Missing Permissions", see Site Configuration).
In any other case a 404 "not found" error is triggered. TYPO3 will invoke the configured error handler.
- TYPO3 9 LTS
- 404: A page/URL that containes a human readable "page not found" message
- 403: A URL that performs a login and a redirect to a supplied URL (eg. extension "felogin")
- the web server must be able to reach itself under the configured domain
Add via composer.json:
"require": {
"plan2net/sierrha": "*"
}
Install and activate the extension in the Extension manager.
Regular Expression For Resource File Extensions:
This is the default regular expression.
css|eot|gif|ico|jpe?g|js(?:on)|png|svg|ttf|webp|woff2?|xml
Enable Debug Mode:
In case of configuration errors a detailed error will be shown when in debug mode or
if the HTTP request comes from an IP listed in $GLOBALS['TYPO3_CONF_VARS']['SYS']['devIPmask'].
Otherwise the error will be passed on to be handled by TYPO3.
