How to create iRule to forward request depending on context input which has hyphen sign "-" in the url

For eg. when user type http://abc.com/aa/bb/cc/xx-yy-zz , iRule should redirect to http://abc.com/aa/bb/cc?t1=xx&t2=yy&t3=zz

 

Explanation

 

http://abc.com/aa/bb/cc/xx-yy-zz [ aa,bb,cc are static values and xx,yy,zz are dynamic values (user provided inputs ) ] http://abc.com/aa/bb/cc?t1=xx&t2=yy&t3=zz [ &,t1,=,xx,t2,t3, are static)

 

Expected result: User inputs xx,yy,zz should sit in the appropriate output context path ie. xx should sit after t1= , yy after t2= , zz after t3=

    Try this

    set newuri {/aa/bb/cc/}
set str [split [lindex [split [HTTP::uri] /] end] -]
set parm "t1=[lindex $str 0],t2=[lindex $str 1],t2=[lindex $str 2]"
HTTP::uri "$newuri?$parm"

    Thank you , I got the clue. Below rule worked for me. But minor issue popping up now.

     

    if { [HTTP::uri] starts_with "/aa/bb/cc/" } { set PREFIX_STATIC "/cs/ccs-cctc/jobs" set XX_VAL [ getfield [HTTP::uri] "-" 2] set YY_VAL [ getfield [HTTP::uri] "-" 3] set ZZ_VAL [ getfield [HTTP::uri] "-" 4] set XX_NEW [split [lindex [split $XX_VAL /] end] -] HTTP::uri "$PREFIX_STATIC?q1=$XX_NEW&q2=$YY_VAL&q3=$ZZ_VAL" }

     

    This iRule only picking the 4 the field value "zz" not adding subsequent values to URI.

     

    For eg. If user hit http://abc.com/aa/bb/cc/xx-yy-zz-blah-blah , endresult should be http://abc.com/aa/bb/cc?q1=xx&q2=yy&q3=zz-blah-blah
