No. Just try it out..
Code:
$ ignoredErrors=(52 403 404 500)
$ for status in {0..10}; do printf "var status: $status "; if [[ "${ignoredErrors[@]}" =~ "$status" ]]; then echo yes; else echo no; fi; done
var status: 0 yes
var status: 1 no
var status: 2 yes
var status: 3 yes
var status: 4 yes
var status: 5 yes
var status: 6 no
var status: 7 no
var status: 8 no
var status: 9 no
var status: 10 no

Tried it but couldn't make it work that way, still take the whole thing as a single option (I think that's why I used the array mode) Smilie
No it does not take it as a single option. It only does so if you put double quotes around it..

Code:
$ curlParameters=(--connect-timeout $timeout --insecure -S -s -f -o /dev/null)
$ printf "%s\n" ${curlParameters[@]}
--connect-timeout
--insecure
-S
-s
-f
-o
/dev/null
$ curlParameters="--connect-timeout $timeout --insecure -S -s -f -o /dev/null"
$ printf "%s\n" ${curlParameters}
--connect-timeout
--insecure
-S
-s
-f
-o
/dev/null

--edit--
But look what happens when you globally change IFS to $'\r\n' like you do in your script:
Code:
$ IFS=$'\r\n'
$ curlParameters="--connect-timeout $timeout --insecure -S -s -f -o /dev/null"
$ printf "%s\n" ${curlParameters}
--co

ect-timeout  --i
secu
e -S -s -f -o /dev/
ull

$ printf "%s\n" ${curlParameters[@]}
--co

ect-timeout
--i
secu
e
-S
-s
-f
-o
/dev/
ull
$ printf "%s\n" "${curlParameters[@]}"
--connect-timeout
--insecure
-S
-s
-f
-o
/dev/null
