DefaultHttpHeadersFactory (Netty API Reference (4.1.116.Final))

java.lang.Object
- io.netty.handler.codec.http.DefaultHttpHeadersFactory

All Implemented Interfaces:

HttpHeadersFactory
```
public final class DefaultHttpHeadersFactory
extends Object
implements HttpHeadersFactory
```
A builder of HttpHeadersFactory instances, that itself implements HttpHeadersFactory. The builder is immutable, and every with- method produce a new, modified instance.
The default builder you most likely want to start with is headersFactory().

  - newHeaders
```
public HttpHeaders newHeaders()
```
    Description copied from interface: HttpHeadersFactory
    
    Create a new HttpHeaders instance.
    
    Specified by:
    
    newHeaders in interface HttpHeadersFactory
  - newEmptyHeaders
```
public HttpHeaders newEmptyHeaders()
```
    Description copied from interface: HttpHeadersFactory
    
    Create a new HttpHeaders instance, but sized to be as small an object as possible.
    
    Specified by:
    
    newEmptyHeaders in interface HttpHeadersFactory
  - withNameValidation
```
public DefaultHttpHeadersFactory withNameValidation(boolean validation)
```
    Create a new builder that has HTTP header name validation enabled or disabled.
    Warning! Setting validation to false will mean that Netty won't validate & protect against user-supplied headers that are malicious. This can leave your server implementation vulnerable to CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') . When disabling this validation, it is the responsibility of the caller to ensure that the values supplied do not contain a non-url-escaped carriage return (CR) and/or line feed (LF) characters.
    
    Parameters:
    
    validation - If validation should be enabled or disabled.
    
    Returns:
    
    The new builder.
  - withNameValidator
```
public DefaultHttpHeadersFactory withNameValidator(DefaultHeaders.NameValidator<CharSequence> validator)
```
    Create a new builder that with the given DefaultHeaders.NameValidator.
    Warning! If the given validator does not check that the header names are standards compliant, Netty won't validate & protect against user-supplied headers that are malicious. This can leave your server implementation vulnerable to CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') . When disabling this validation, it is the responsibility of the caller to ensure that the values supplied do not contain a non-url-escaped carriage return (CR) and/or line feed (LF) characters.
    
    Parameters:
    
    validator - The HTTP header name validator to use.
    
    Returns:
    
    The new builder.
  - withValueValidation
```
public DefaultHttpHeadersFactory withValueValidation(boolean validation)
```
    Create a new builder that has HTTP header value validation enabled or disabled.
    Warning! Setting validation to false will mean that Netty won't validate & protect against user-supplied headers that are malicious. This can leave your server implementation vulnerable to CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') . When disabling this validation, it is the responsibility of the caller to ensure that the values supplied do not contain a non-url-escaped carriage return (CR) and/or line feed (LF) characters.
    
    Parameters:
    
    validation - If validation should be enabled or disabled.
    
    Returns:
    
    The new builder.
  - withValueValidator
```
public DefaultHttpHeadersFactory withValueValidator(DefaultHeaders.ValueValidator<CharSequence> validator)
```
    Create a new builder that with the given DefaultHeaders.ValueValidator.
    Warning! If the given validator does not check that the header values are standards compliant, Netty won't validate & protect against user-supplied headers that are malicious. This can leave your server implementation vulnerable to CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') . When disabling this validation, it is the responsibility of the caller to ensure that the values supplied do not contain a non-url-escaped carriage return (CR) and/or line feed (LF) characters.

```
public DefaultHttpHeadersFactory withCombiningHeaders(boolean combiningHeaders)
```
    Create a new builder that will build HttpHeaders objects that either combine multi-valued headers, or not.
    
    Parameters:
    
    combiningHeaders - true if multi-valued headers should be combined, otherwise false.
    
    Returns:
    
    The new builder.
  - getNameValidator
```
public DefaultHeaders.NameValidator<CharSequence> getNameValidator()
```
    Get the currently configured DefaultHeaders.NameValidator.
