converting regex to irule

Can you give a few sample strings for each case? We should be able to adapt this to iRule code using scan or string commands instead of regexes for better performance.

The answer is definitely yes. As Aaron indicated, using something other than regular expressions will likely be vastly superior performance wise. Regular expressions are powerful and when necessary iRules can certainly allow you to use them, but we tend to recommend them as a last option.

I've managed to get all the rules working accept for this one

 

category archive page: match url="^Archive/([A-Za-z\-0-9.]+)/([0-9]+)/([0-9]+)(/)" url="archive.aspx?cat_id={R:2}&pg={R:3}

 

 

} elseif { [scan [HTTP::uri] {/Archive/%[A-Za-z\-0-9.]/%[0-9]/%[0-9]} s1 s2 s3] == 3 } {

 

scan [HTTP::uri] {/Archive/%[A-Za-z\-0-9.]/%[0-9]/%[0-9]} s1 s2 s3

 

log -noname local0. "$s1 $s2 $s3"

 

HTTP::respond 301 Location "http://[HTTP::host]/archive.aspx?cat_id=$s2&pg=$s3"

 

 

I'm not sure how to simulate the (+) as when i try add it in i get the following error on the f5
