Function Documentation

◆ matchDomainName()

int matchDomainName ( const char *  host,
const char *  domain,
uint8_t  flags = mdnNone 
)

matchDomainName() matches a hostname (usually extracted from traffic) with a domainname when mdnNone or mdnRejectSubsubDomains flags are used according to the following rules:

HOST DOMAIN mdnNone mdnRejectSubsubDomains
foo.com foo.com YES YES
.foo.com foo.com YES YES
x.foo.com foo.com NO NO
foo.com .foo.com YES YES
.foo.com .foo.com YES YES
x.foo.com .foo.com YES YES
.x.foo.com .foo.com YES NO
y.x.foo.com .foo.com YES NO

if mdnHonorWildcards flag is set then the matchDomainName() also accepts optional wildcards on hostname:

HOST DOMAIN MATCH?
*.foo.com x.foo.com YES
*.foo.com .x.foo.com YES
*.foo.com .foo.com YES
*.foo.com foo.com NO

The combination of mdnHonorWildcards and mdnRejectSubsubDomains flags is supported.

Return values
0means the host matches the domain
1means the host is greater than the domain
-1means the host is less than the domain

◆ uriParseScheme()

static AnyP::UriScheme uriParseScheme ( Parser::Tokenizer tok)
static

Extract the URI scheme and ':' delimiter from the given input buffer.

Schemes up to 16 characters are accepted.

Governed by RFC 3986 section 3.1

◆ urlAppendDomain()

bool urlAppendDomain ( char *  host)

Appends configured append_domain to hostname, assuming the given buffer is at least SQUIDHOSTNAMELEN bytes long, and that the host FQDN is not a 'dotless' TLD.

Returns
false if and only if there is not enough space to append

◆ urlCanonicalCleanWithoutRequest()

char* urlCanonicalCleanWithoutRequest ( const SBuf url,
const HttpRequestMethod method,
const AnyP::UriScheme scheme 
)
Todo:
AYJ: Performance: This is an almost duplicate of HttpRequest::effectiveRequestUri(). But elides the query-string. After copying it on in the first place! Would be less code to merge the two with a flag parameter. and never copy the query-string part in the first place

◆ urlCanonicalFakeHttps()

const char* urlCanonicalFakeHttps ( const HttpRequest request)

Yet another alternative to urlCanonical. This one adds the https:// parts to Http::METHOD_CONNECT URL for use in error page outputs. Luckily we can leverage the others instead of duplicating.
