SPECweb2009 Release 1.20 E-commerce Workload Pseudocode

Version 1.20, Last modified 2010-04-29

The pseudo code specification provided is a description of the actual work that needs to be implemented. This is required so that results will be comparable. Any dynamic implementation must follow the specification exactly. This means that all operations specified, such as loops and searches, should be executed for each request. Unless otherwise specified, results or intermediate results from previous operations or requests should not be cached.

To provide the flexibility needed to implement this code on any platform and in any desired scripting language, the subroutines listed in the pseudo code may be inlined or subdivided into smaller subroutines as long as the algorithms implemented by the subroutines are performed exactly as described.

The dynamic operations must be executed by separate dynamic modules. The dynamic code must be written in a widely-used scripting language. Script implementations in PHP and JSP are supplied with the kit.

1.1.1 Definitions of Terms

BESIM
Backend Simulator, that resides on a separate physical machine than the primary SUT.  See User's Guide for more details.
QUERYSTRING
Information following the '?' in the URL.
PADDING
A file generated by wafgen that brings the dynamic script up to the sizes observed in real-world pages (that use JavaScript, CSS, etc.)
SESSION_ARRAY
A property of the scripting engine that provides some stateful way of maintaining variables across page executions (may not necessarily be an array)
Redirect
A case where the web server must send back HTTP status code 307, along with a "Location:" header indicating the URL the client will be redirected to.

Note: Directories are specified in this document with a forward slash, '/', however, this in no way implies that one has to follow this convention. Use what works on one's operating system.

1.1.2 Specification of Return Formats

All of the dynamic requests return one of the following types of HTML pages to the client. These formats must be followed precisely for the client software to understand the returned pages. This includes the blank line between the headers and the <html> tag.

Square brackets, [], are used to denote either a looping construct (If/Else/End If, Foreach, etc.), or where appropriate text should be substituted. This text should contain only the required information.  The text may NOT be padded in any way to create a fixed length field.

Curly braces, {}, are used to denote an array that can contain multiple variables inside of it.  Arrays are not strictly required for implementing these constructs; they are used to indicate a logical grouping of variables.

Extra headers required by the web server are allowed. The formats simply show the minimum required by the benchmark.
