CirrostratusHi,
The previous example would search the path and trigger the log statement if the path contained a space or encoded versions of a space. If you want to instead check for / and any alphanumeric character you could use scan ():
when HTTP_REQUEST {
Use scan to read in all characters from a-z, A-Z, 0-9 and /
Check if the scanned string is not the entire path
if {[scan [HTTP::path] {%[a-zA-Z0-9/]}] ne [HTTP::path]}{
log local0. "Path contained non-alphanumerics and /: [HTTP::path]. matched up to [scan [HTTP::path] {%[a-zA-Z0-9/]}]"
}
}
