iRule Explanation - from the iRules Toolbox

Source: path_parsing_with_glob_style_matching.txt

# Create an F5 BIG-IP iRule that routes HTTP requests to different pools based on the first two characters of the URL path. The rule should use case-insensitive matching and handle paths starting with /a, /b, and /c, followed by specific ranges of letters. Include a default case for paths that don't match any specified patterns. The rule should have default priority and use efficient matching techniques.

when HTTP_REQUEST priority 500 {
    # Parse the first then second character in the path
    # Convert the path to lowercase for case-insensitive matching
    switch -glob -- [string tolower [HTTP::path]] {
        # If path starts with /a followed by a-l, route to this pool
        "/a[a-l]*" {
            pool reward-uat5.123.com_AA2AL
        }
        # If path starts with /a followed by m-z, or /b followed by a-l, route to this pool
        "/a[m-z]*" -
        "/b[a-l]*" {
            pool reward-uat5.123.com_AM2BL
        }
        # If path starts with /b followed by m-z, or /c followed by a-d, route to this pool
        "/b[m-z]*" -
        "/c[a-d]*" {
            pool reward-uat5.123.com_BM2CD
        }
        # Default case: if none of the above patterns match (including just a forward slash)
        default {
            # Route to the first pool as a fallback
            pool reward-uat5.123.com_AA2AL
        }
    }
}

Explanation (generated by F5 Distributed Cloud AI Assistant):

Objective
• This iRule routes incoming HTTP requests to different server pools based on the first two characters of the URL path.
• It performs case-insensitive matching by converting the path to lowercase.
• Paths beginning with /a (subdivided into a-l and m-z), /b (a-l and m-z), and /c (a-d) each map to a specific pool.
• Any path not matching these patterns (including /) falls back to the first pool.

Execution Flow

The HTTP_REQUEST event fires with priority 500.

[HTTP::path] is converted to lowercase using string tolower.

switch -glob -- evaluates the lowercase path against patterns, in order:
• Pattern /a[a-l]* → pool reward-uat5.123.com_AA2AL
• Patterns /a[m-z]* OR /b[a-l]* → pool reward-uat5.123.com_AM2BL
• Patterns /b[m-z]* OR /c[a-d]* → pool reward-uat5.123.com_BM2CD
• default (any other path) → pool reward-uat5.123.com_AA2AL

Potential Logic Concerns
• The rule explicitly sets priority 500, which differs from the requested default priority (omit priority for default behavior). (high confidence)

Overall Summary
The iRule efficiently implements case-insensitive, glob-based matching for the specified path ranges with a clear default fallback. Adjusting or removing the explicit priority 500 will align it with the requested default priority.
