Hi I am new to nDPI and have enjoyed using the features of nDPI. While i was learning about it I got struct by a query where i cant find any answer regarding it please help me to resolve my query

Branch : 4.0-stable

So my questions are
1.Is URL information is updated only during HTTP response?
2. If so with provided WebattackRCE.pcap there are only get requests no response information
3. when i used this pcap to verify the results nDPI couldn't identify risk as "RCE Injection" as there were no response packets to fill out url info for risk detection.
4. But in WebattackRCE.pcap.out file (in dev branch) i am able to view risk as "RCE Injection"

Could anyone correct me if I my understanding is wrong or correct.

This was contributed code that might be imperfect. I see sometimes false positives. I would appreciate if you could fix the issues you have noticed.

@v-crypto, keep in mind that to have RCE detection you need to have PCRE support, via --with-pcre flag
