Why do random ?jdfwkey=0plwb1 characters appear at the end of the URL when visiting the website? Does it affect normal access?

1. Why do random ?jdfwkey=0plwb1 characters appear after the URL when visiting a website, and will this affect normal access?

Answer: Some virtual hosts of our company have enabled hardware firewall protection. When the server is attacked, protection is automatically activated. ?jdfwkey=0plwb1 is a random parameter generated by automatic protection and will not affect normal access. Of course, attacks and abnormal access will be intercepted.

2. Does it affect search engine indexing?

Answer: It will not affect indexing by any search engine or spider crawling, because spider pass-through is configured on the hardware firewall.

3. Will it cause some website functions to be unavailable? Will it affect website parameter calls?

Answer: Theoretically, it will not affect the use of any website function. In principle, it will not affect parameter calls either. If it does have an impact, it is recommended to enable Baidu Cloud Protection, and ?random characters will no longer appear after the URL address.
