As sessions are side* The module will be available if the {{Code|basex-effecting operations, all functions api}} library is found in this module are flagged as ''non-deterministic''the classpath. This means that is the evaluation order case if you use one of the functions will not be influenced by the compilercomplete distributions of BaseX (zip, exe, war). * All functions and errors are assigned to the {{Code|<code><nowiki>http://basex.org/modules/session}} </nowiki></code> namespace, which must be dynamically imported. In this documentation, the namespace is statically bound to the {{Code|session}} prefix. * If any of the functions is called outside the servlet context, <code>[[XQuery Errors#BaseX Errors are assigned to the {{Code|basex:http:]]<//basexcode> is raised.* As sessions are side-effecting operations, all functions are flagged as ''non-deterministic''.org/errors}} namespaceAs a result, which is statically bound to the {{Code|bxerr}} prefixsome query optimizations will be suppressed.
