What is the bSession cookie?
bSession is a first-party cookie belonging to the Wix platform, found on any website built and hosted with the Wix editor. It is generated automatically by Wix's infrastructure the first time a visitor loads a page, regardless of the actions they take.
It is not set directly by the site owner; instead it is part of the underlying technical operation of the Wix platform the site runs on.
What data it stores
The cookie stores a server-generated session identifier used to recognize requests from the same visitor during a visit. The exact value format may vary and is internal to Wix's platform.
The data is sent to Wix's servers, which manage the site's technical infrastructure, including traffic distribution across servers.
What it is used for
According to Wix's public documentation, bSession is used for load balancing between the server instances serving the site, so that requests from the same visitor are routed consistently.
Wix also references it in the context of measuring site usage, which is why CookieFix classifies it under the statistics category.
Does it require consent?
CookieFix classifies bSession under the statistics category. Cookies in this category are not strictly necessary for the site's basic operation, so they require prior visitor consent under the ePrivacy Directive (as transposed in Romania by Law 506/2004) and the GDPR.
- The site owner must declare it in the cookie policy, with its actual purpose and duration.
- The cookie should not be set/activated before the visitor gives consent for the statistics category.
How to block or delete bSession
A visitor can delete or block this cookie from their browser settings (Chrome, Firefox, Edge, Safari), under the site data/cookie management section. Blocking it may affect the page's proper functioning, since Wix also relies on it at the infrastructure level.
For site owners, a CMP such as CookieFix can automatically block the script that generates this cookie until the visitor consents to the statistics category, helping meet prior-consent requirements.
