spaces in http monitor recieve string?

TEST\sBLAH should work, according to this sol (if I'm reading it right):

N

yeah not working :\

i also tried \sBLAH and TEST\s with no luck.

TEST[ ]BLAH?

negative :(

I apologize for the following "you probably already checked these but i don't know that" questions...

I use a lot of monitors looking for response code strings like "200 OK", which are configured as receive strings and work as expected:

1. Are you sure it's a single space between TEST and BLAH, and not multiple spaces or a different whitespace character?
2. Have you tried using curl and then copying/pasting the expected response into the receive string?
3. Have you tried looking for other text on the health check page that contain similar text?

The text is in the http body and I copied it, like you said. There may be something in the body that's causing it to be escaped.. or maybe there's a max length that can be searched by a monitor? I'm testing different chunks of the source now to find where it dies.
