26.09.2017 12:40:42.804 *INFO* [0:0:0:0:0:0:0:1 [1506447642680] GET /content/we-retail/language-masters/en.html HTTP/1.1] AntiSamy warning: The a tag contained an attribute that we could not process. The rel attribute had a value of "bookmark". This value could not be accepted for security reasons. We have chosen to remove this attribute from the tag and leave everything else in place so that we could process the input.

To make rel accepted,  make the following changes in /apps/cq/xssprotection/config.xml (overlaying /libs/cq/xssprotection/config.xml), for Sightly/HTL its /libs/sling/xss/config.xml


1) Login to CRXDE Lite, create folder (nt:folder) /apps/eaem-touchui-extend-rte-link-options

2) Create clientlib (type cq:ClientLibraryFolder/apps/eaem-touchui-extend-rte-link-options/clientlib and set property categories of String type to cq.authoring.dialog.all and dependencies String[] to lodash

3) Create file ( type nt:file ) /apps/eaem-touchui-extend-rte-link-options/clientlib/js.txt, add the following


4) Create file (type nt:file) /apps/eaem-touchui-extend-rte-link-options/clientlib/link-options.js, add the following code

    It's awesome concept, it's works fine in my local server. But same is not working my production server in author instance, it's working in my production server in publish server. I think xssprotection have some restriction for security reasons. could you please give me proper solution for production author server.
