Stream Expressions

I think these are the matches Russell is trying to match/replace:

 

 

http://csweb -> https://csweb

 

http://www.quantum.com(?!http://www.quantum.com/ProductAwareTandC.aspx) -> https://www.quantum.com

 

http://maps.google.com -> https://maps.google.com

 

 

The second one is possibly causing the issue. I think you want this regex instead:

 

 

@http://www\.quantum\.com(?!/ProductAwareTandC\.aspx)@https://www.quantum.com@

 

 

If you want to do this without case sensitivity on the capitalized letters, you can use a character set:

 

 

@http://www\.quantum\.com(?!/[pP]roduct[aA]ware[tT]and[cC]\.aspx)@https://www.quantum.com@

 

 

If that regex doesn't work and you can't do this with negative lookaheads, you might try a more generic stream expression like @http://www\.quantum\.com[a-zA-Z0-9/?_-]*@@ and then check the matched string using STREAM::match in STREAM_MATCHED to determine whether to rewrite the protocol.

 

 

There's an example of this on the STREAM::expression wiki page:

This example shows how you can use in the event to check if the matched string meets some condition that can't easily be checked for using a single regex in .

 

 

 

Note that you should escape the periods in the "find" portion of the stream expression so they match on a literal period instead of any single character.
