Description
It appears that whitespace causes weird behavior with header_rewrite, for example:
If you remove the white space before the = and the quotes it appears to behave correctly. This whitespace issue is likely to cause strange bugs and needs to be fixed.
cond %{READ_REQUEST_HDR_HOOK}
cond %{CLIENT-HEADER:Host} /^localhost$/ [AND]
cond %{CLIENT-HEADER:non_existent_header} = "shouldnt_exist_anyway" [AND]
add-header X-HeaderRewriteApplied true
With the following request:
curl -v localhost/
Header_rewrite will incorrectly apply the rule:
