Use the following special characters as indicated:

• Parentheses () to enclose parameters
• Commas , to separate parameters
• Forward slashes / to separate type declarations from a value in a parameter

• Backslashes \

  • To search for a backslash \

    GetString().Find(\\)

  • To split a string by a backslash \

    GetString.split(\\\\).[0]

• Dots . to separate methods and properties in the getter chain
• Dot . to represent "anything" must be escaped

• Curly braces { } to delineate getter chains from static elements in custom expressions on HTTPRequest objects (including in the Java Servlet Transaction Naming Configuration window and in the Split Transactions Using Request Data tab of the servlet custom match and exclude rules)

Getter chains also treat spaces at the beginning or end of a string as special characters.
