Passing matrix parameters to show and list

Hello,

Does anyone know if it's possible to pass matrix parameters to show and list
functions?

I tried the following rewrite rule: {"from" : "myshow/:id/:extra",  "to":
"_show/myshow/:id"}

_rewrite/myshow/myid/path;m1=v1;m2=v2
is translated to
_show/myshow/myid?id=myid&extra=path%3Bm1%3Dv1%3Bm2%3Dv2
so I have
req.query.extra == "path;m1=v1;m2=v2" and can parse it manually.

But if I use special characters things break, e.g. I want to pass "a;b=c" as
a value for m2:

_rewrite/myshow/myid/path;m1=v1;m2=a%3Bb%3Dc
is translated to
_show/myshow/myid?id=myid&extra=path%3Bm1%3Dv1%3Bm2%3Da%3Bb%3Dc
so I have
req.query.extra == "path;m1=v1;m2=a;b=c" and cannot parse it correctly.

Thanks,
Taras

Thank you,

I just wanted to use matrix parameters [1] but query should work for me too.

You can do :

_rewrite/myshow/myid/path?m1=v1&m2="a;b=c"

then req.query should be ok.
