iRule to Add Trailing Slash Except for Extensions
Hello,
I have an iRule that I am using to direct requests to a specific pool based on the URI:
when HTTP_REQUEST {
set uri [string tolower [HTTP::uri]]
if {[HTTP::uri] starts_with "/apps"} {
pool ProxyPass_DEV_pool_2
}
else {
pool ProxyPass_DEV_pool_1
}
}
This is working fine, but I also need to ensure that any request that does not have an trailing slash "/" at the end, gets it added, with the exception of requests that end in an extension. For example: www.website.com/apps would become www.website.com/apps/, but for any URI really.
Additionally, www.website.com/test.html would not be affected.
Any suggestions? Thanks!
Hello,
Considering that the resource will only have the dot char to extensions, I do this way:
when HTTP_REQUEST { if { not ( [HTTP::path] ends_with "/") && not ( [URI::basename [HTTP::uri]] contains "." ) } { # Append slash and keep querystring when it exists HTTP::uri [HTTP::path]/[expr { "[URI::query [HTTP::uri]]" eq {} ? {} : "?[URI::query [HTTP::uri]]" }] } if { [string tolower [HTTP::uri]] starts_with "/apps" } { pool ProxyPass_DEV_pool_2 } else { pool ProxyPass_DEV_pool_1 } }
Where:
- "/apps" will become "/apps/" internally;
- "/apps?param=value" will become "/apps/?param=value" internally;
- "/test.html" and "/test.html?param=value" remais the same.
I hope it helps.
Regards
