Its barracuda includes two new row record formats: COMPRESSD and dynamic. The new two record format pairs the data stored in the BLOB in a full row overflow, only 20 bytes of pointers in the data page, the time data stored in the off page. And the previous compact

Waf xss bypass posture
Due to the wide use of application firewalls, it is necessary to test WAF's ability to defend against xss attacks. Of course, all the experiments are to prove that the vendor must eliminate the vulnerability from the root cause, and cannot lie on the WAF without any worries.Some popular WAF such as F5 Big IP, Imperva Incapsula, AQTRONIX WebKnight, PHP-IDS, Mod-Security, Sucuri, QuickDefense, and Barracuda WAF are all tested. byp
