NimbostratusRemoving / inserted by iRule variable
Is there a way to prevent the / from being inserted when using variables? The following iRule works to redirect users from /29900 to /Templates/IQuote010.cfm?ID=/29900. I need a way to remove the / between ID=/29900 so the uri looks like /Templates/IQuote010.cfm?ID=29900.
/29900 (initial uri)
/Templates/IQuote010.cfm?ID=29900 (uri should look like this)
/Templates/IQuote010.cfm?ID=/29900 (need to remove the /)
when HTTP_REQUEST {
set uri [HTTP::uri]
set host [HTTP::host]
set new_uri /Templates/IQuote010.cfm?ID=
set new_url $host$new_uri$uri
if { [HTTP::uri] starts_with "/Templates" } {
use pool UITShared-172-29-98-77
}
else {
HTTP::redirect http://$new_url
}
}
- Try changing the "set uri" line to:
set uri [string trimleft [HTTP::uri] "/"] 
Aaron_Magruder_Thanks. This worked like a champ. I think there is a better way to accomplish this but I'm not sure how. The current way I have configured it, I will need to include any new directories in the rule. We would like to look for 5 digits in the uri. If there are only 5, then we would like to redirect to /Templates/.... Everything else would use the pool. This would prevent use from having to add new directories to the rule.
If you have any ideas, let me know.
when HTTP_REQUEST {
set uri [string trimleft [HTTP::uri] "/"]
set host [HTTP::host]
set new_uri /Templates/IQuote010.cfm?ID=
set new_url $host$new_uri$uri
if { [HTTP::uri] starts_with "/Templates" or [HTTP::uri] starts_with "/images" } {
use pool UITShared-172-29-98-77
}
else {
HTTP::redirect http://$new_url
}

Would this work? Sorry, I don't have a pair with which to test right now, F5 pried our evaluation units out of our hands last Friday. Hopefully a PO will be cut soon.
when HTTP_REQUEST {
set uri { string trimleft [http::uri] "/" }
set uri_length { string length $uri }
set host [HTTP::host]
set new_uri /Templates/IQuote010.cfm?ID=
set new_url $host$new_uri$uri
if { $uri_length = 5 } {
HTTP::redirect http://$new_url
log "Redirecting [IP::client_addr] to http://$new_url"
}
else {
use pool UITShared-172-29-98-77
}
} - JRahmI think that can be chopped down:
when HTTP_REQUEST {
set uri { string trimleft [http::uri] "/" }
set url [HTTP::host]/Templates/IQuote010.cfm?ID=
if { string length $uri = 5 } {
HTTP::redirect http://$url$uri
log "Redirecting [IP::client_addr] to http://$url$uri"
}
else {
use pool UITShared-172-29-98-77
}
} - Aaron_Magruder_Neither of those options worked. The LTM didn't send the redirect.
when HTTP_REQUEST {
set uri { string trimleft [http::uri] "/" }
set uri_length { string length [http::uri] }
set host [HTTP::host]
set new_uri /Templates/IQuote010.cfm?ID=
set new_url $host$new_uri$uri
if { [string length http::uri] equals 5 } {
HTTP::redirect http://$new_url
}
else {
use pool UITShared-172-29-98-77
}
} - JRahmIn this line:
if { [string length http::uri] equals 5 }
The unformatted uri still has the / in it, are you including that in the 5 characters, or should it be 6 with the /. Otherwise, you could use the $uri variable. Add some logging for debugging purposes that shows you the output of the string manipulations, such as
set uri_length { string length [HTTP::uri] }
set uri__formatted_length { string length $uri }
log " URI is [HTTP::uri] "
log " URI formatted is $uri "
log " URI lenght is $uri_length "
log " URI formatted length is $uri_formatted_length "
