NimbostratusiRule exclude URI
I am fairly new to iRules so any help greately appreciated.
What is correct syntax to exclude URI "/abc/Web123/cde/forum123/ from receiving HTTP code 200 and the message "123456789"? Is the exclamation mark a orrect synatx to exclude URI?
Here is iRule
when HTTP_REQUEST {
set http_path [ string tolower [HTTP::path]]
if { ! ($http_path starts_with "/abc/Web123/cde/forum123") } {
HTTP::respond 200 content "
<html>
<head>
<title></title>
</head>
<body>
123456789
</body>
</html>
"
}
}
Thank you for any assistamce you can provide.
To negate starts_with I would use the not operator:

when HTTP_REQUEST { if { not ([HTTP::uri] starts_with "/abc") } { # do something ... } else { # do something else... } }For excluding the exact path, you can go with the "ne" operator

mihaicAs far as i know you can use ! or NOT.
Here are the operators list:

Hi Alex_Pintel ,
Could you please try this :when HTTP_REQUEST { #set http_path [ string tolower [HTTP::path]] if { [HTTP::path] ne "/abc/Web123/cde/forum123" } { HTTP::respond 200 content " <html> <head> <title></title> </head> <body> 123456789 </body> </html> " } }I tested it on my lab and it works well.
Regards
CA_ValliHello, if you're looking to exclude an exact match for a string, "ne" operator can be used as well.
One thing I noticed -- since this is an exact match, be careful with "string tolower" syntax as it will convert everything to lowercase, so you will never see Web123 -- it's gonna be web123 instead.
I generally don't recommend converting paths to lowercase since it is case sensitive, try using this instead:
if { [HTTP::path] ne "/abc/Web123/cde/forum123" }{ ... }
Alex_PintelThank you all for responding to my post. I have another question.
What would be right syntax if I need to use 2 URLs?
if { [HTTP::path] ne "/abc/Web123/cde/forum123" OR "/abc/Web123/cde/forum456"Is the "OR" correct operator?
Thank you!

For the requested logic, you need the "and" operator between two tests:
if { ([HTTP::path] ne "/abc/Web123/cde/forum123") and ([HTTP::path] ne "/abc/Web123/cde/forum456") }If you plan to add more paths in the future, then consider using a switch test
