http to https redirect

Here is a very generic approach, ripped right from the ask.f5.com solutions (SOL3847 to be exact). This one redirects all traffic to its https counterpart:

  
 rule redirect_rule {  
 when HTTP_REQUEST {  
 HTTP::redirect https://[HTTP::host][HTTP::uri]  
 }  
 }  
 

The only difference here is that you want to do some basic URI switching (also note that you can accomplish a similar thing with an HTTP class profile, so you may want to check that option out as well).

I think you may be looking for "contains" instead of "equals"; at the bottom of your post you indicate a "*", which tells me there's more stuff following '/this/directory/', which may not match exactly. I don't have a lab box handy but this should get you close:

  
 when HTTP_REQUEST {  
 if { [HTTP::uri] contains "/this/directory/" } {  
 HTTP::redirect https://[HTTP::host][HTTP::uri]  
 }  
 }  
 

I hope this helps,
