[cgiapp] CAP Dispatch and encoded backslashes

[B. Estrade]

I am having an issue with CAP Dispatch that seems to be rearing its
ugly head when I send, as part of the route, serialized JSON data.
The issue is that I have a value with a backslash in it.

I am pretty sure the URL parsing done by Dispatch is splitting on this
backslash, but I though that it wouldn't be a problem since it's being
sent as an encoded string.

When I don't include this one field, it works; when I do, I get a 404
thrown by Dispatch.

Any ways around this?

Thanks,
Brett
