true if headers indicates transfer-encoding chunked, false otherwise.

domainMatches

public static boolean domainMatches(CharSequence requestDomain,
 @Nullable
 CharSequence cookieDomain)

Domain Matching.

Parameters:

requestDomain - The domain from the request.

cookieDomain - The domain from the cookie.

Returns:

true if there is a match.

pathMatches

public static boolean pathMatches(CharSequence requestPath,
 @Nullable
 CharSequence cookiePath)

Path Matching.

Parameters:

requestPath - The path from the request.

cookiePath - The path from the cookie.

Returns:

true if there is a match.

isSetCookieNameMatches

public static boolean isSetCookieNameMatches(CharSequence setCookieString,
 CharSequence setCookieName)

Determine if a set-cookie-string's cookie-name matches setCookieName.

Parameters:

setCookieString - The set-cookie-string.

setCookieName - The cookie-name.

Returns:

true if a set-cookie-string's cookie-name matches setCookieName.

parseSetCookie

@Nullable
public static HttpSetCookie parseSetCookie(CharSequence setCookieString,
 CharSequence setCookieName,
 boolean validate)

Parse a HttpSetCookie from a set-cookie-string.

Parameters:

setCookieString - The set-cookie-string.

setCookieName - The cookie-name.

validate - true to attempt extra validation.

Returns:

a HttpSetCookie from a set-cookie-string.

parseCookiePair

@Nullable
public static HttpCookiePair parseCookiePair(CharSequence cookieString,
 CharSequence cookiePairName)

Parse a single cookie-pair from a cookie-string.

Parameters:

cookieString - The cookie-string that may contain multiple cookie-pairs.

cookiePairName - The cookie-name identifying the cookie-pairs to parse.

Returns:

• The first cookie-pair from a cookie-string whose cookie-name matched cookiePairName
• null if no matches were found

removeCookiePairs

@Nullable
public static CharSequence removeCookiePairs(CharSequence cookieString,
 CharSequence cookiePairName)

Remove a single cookie-pair for a cookie-string.

Parameters:

cookieString - The cookie-string that may contain multiple cookie-pairs.

cookiePairName - The cookie-name identifying the cookie-pairs to remove.

Returns:

• The cookie-string value with all cookie-pairs removed whose cookie-name matches cookiePairName
• Empty if all the cookie-pairs matched cookiePairName
• null if none of the cookie-pairs matched cookiePairName

hasContentType

public static boolean hasContentType(HttpHeaders headers,
 CharSequence expectedContentType,
 @Nullable
 Charset expectedCharset)
