Hi guys I need your need.

Let’s say I have a url ([example.com/apps/test.](http://example.com/apps/test.))

I want this exact url to work, and anything else that’s not that url to redirect to ([example.com](http://example.com))

Hi&nbsp; @mj16othman &nbsp;,&nbsp;  
Try this :

```tcl
when HTTP_REQUEST {
if { [string tolower "[HTTP::host][HTTP::path]"] contains "example.com/apps/test" }{
	return 
	} else { 
	
	#HTTP::redirect "http://example.com"
	HTTP::redirect "http://[HTTP::host]"
	}
}

```

\> you must assign the default pool to that virtual server.&nbsp;  
use only one of those redirections&nbsp; :&nbsp;  
HTTP::redirect “[http://example.com](http://example.com)”  
HTTP::redirect “http://[HTTP::host]”

I hope this helps you

The iRule posted by&nbsp;&nbsp;should work, but you can clean it up a bit. Here we do the following:- More efficient string comparison using starts\_with rather than contains. Also, more secure as a URL may be odd and repeat that string as part of URI path (unlikely though).

- Removed unnecessary comparison for host header. Likely there is no virtual hosting, so all (and only) [example.com](http://example.com) traffic hitting the virtual server. We only need it for return if path doesn’t match our pattern.

- Support both https and http protocols. In case you perform or what to add SSL termination or what not.

- You could also get fancier and support multiple paths you want to check via data groups, or even use a variable for the comparison string portion

So here we have it.

when HTTP\_REQUEST {  
if { [string tolower [HTTP::path]] starts\_with “/apps/test” }{  
return  
} else {  
if { [TCP::local\_port] == 443 }{  
HTTP::redirect “https://[HTTP::host]”  
} else {  
HTTP::redirect “http://[HTTP::host]”  
}  
}  
}

Sorry for the formatting, but posting TCL code via the iPhone triggers an error on DevCentral!

"Correct the highlighted errors and try again.

Post flooding detected (community received posts of a unique message more than 1 times within 3,600 seconds)"

Thats even with just a simple “test” using the TCL \</\> option in the WYSIWYG editor. Strange.

Hi&nbsp; @whisperer &nbsp;,&nbsp;  
Thanks a lot ,&nbsp;  
I have tested it in my internal Lab , it worked as expected for HTTP only however he can do the same for HTTPS but with offloading and redirecting to https at least.&nbsp;

@Mohamed_Ahmed_Kansoh &nbsp;Correct, for HTTPS you would need to have an appropriate VS with client SSL profile and listening on standard port 443. I always think about writing generic iRules so you can resume them for multiple applications.

@whisperer &nbsp;,&nbsp;

Tagging&nbsp; @LiefZimmerman &nbsp;so he can see your issue with sharing TCL code from your phone triggering a post flooding timeout.
