Subject Re: [users@httpd] XSS Issue in v2.0.59
Date Tue, 02 May 2017 06:22:05 GMT
XSS is a vulnerability of the application running on top of web-server 
and browser, there's hardly a way to fix it on a web-server level. But 
outdated web-server may have vulnerabilities of its own.

Of the ways you listed #1 without #2 usually doesn't work; OTOH #2 done 
comprehensively (with some library) usually helps. But it has nothing to 
do with Apache.


With Best Regards,
