NimbostratusHi,
There are two possible methods, either split the uri to get just the first directory, or use glob pattern matching (this is probably the most extensible)...
switch -glob [string tolower [HTTP::uri] ] {
"/abc*" { pool www }
"/cde*" {
HTTP::header insert Header1 domain2
HTTP::header replace Host www.domain.com
HTTP::uri "/domain2[HTTP::uri]"
pool www
}
default { discard }
}
If you do want to get just the first/base directory name you could use something like [getfield [HTTP::uri] "/" 2] - this would get the second field from the uri, using a field seperator of "/". So you'd get something like "abc" or "cde", you might to add a leading slash (/) back when you want to use it.
It's also possible you would need to do further processing to remove parameters in the uri (eg /abc?var=value, or /abc;jsessionid=x).
Another alternative would be to use the subtr command to retrieve a know number of characters (if your base directories all have just 3 character names) - [substr [HTTP::uri] 0 4]
