This is a fork of webkitpdf with compatibility to TYPO3 12.4 and 13.4. Furthermore there is rudimentary DoS protection added. With the TypoScript configuration plugin.tx_webkitpdf_pi1.numberOfUrlsAllowedToProcess the number of URLs per request is limited. By default it's 3. Set it to 0 to allow an unlimited number of URLs. But be aware that a attacker could pass so many URLs that the server breaks down.
Original documentation is still valid: https://github.com/DMKEBUSINESSGMBH/webkitpdf/blob/master/Documentation/Manual.pdf
Caution since Version 2.0.0 The extension now uses namespaces and the TypoScript files have been moved from static/* to Configuration/TypoScript/* so make sure to adjust the paths or reinsert the static TypoScript.
Caution in TYPO3 12.4 and 13.4 When updating from previous versions you need to execute the upgrade wizard.
