Function Documentation

◆ matchDomainName()

int matchDomainName ( const char *  host,
const char *  domain,
MatchDomainNameFlags  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 ,
const AnyP::UriScheme  
)

call HttpRequest::canonicalCleanUrl() instead if you have HttpRequest

Returns
a pointer to a local static buffer containing request URI that honors strip_query_terms and %-encodes unsafe URI characters

Referenced by HttpRequest::canonicalCleanUrl(), ClientHttpRequest::setErrorUri(), and ClientHttpRequest::setLogUriToRawUri().

◆ 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.

◆ urlCheckRequest()

◆ urlInitialize()

void urlInitialize ( void  )

◆ urlIsRelative()

bool urlIsRelative ( const char *  url)

Test if a URL is a relative reference.

Governed by RFC 3986 section 4.2

relative-ref = relative-part [ "?" query ] [ "#" fragment ]

relative-part = "//" authority path-abempty / path-absolute / path-noscheme / path-empty
