<Fmt: requestEncoding> tag
<Fmt: requestEncoding> tag is used to specify a return to the Web application form encoding type.
Syntax
<fmt:requestEncoding value="<string>"/>
Attributes
<Fmt: requestEncoding> tag has the following attributes:| Attributes | description | If necessary | Defaults |
|---|---|---|---|
| key | The name of the character encoding set for decoding the request parameters | Yes | no |
Use <fmt: requestEncoding> tag to specify the character set for decoding the data from the form. This tag must be used when the character set is not ISO-8859-1. Because most browsers do not contain Content-Type header in their requests, so need this tag.
<Fmt: requestEncoding> tag is used to specify the purpose of Content-Type request. You must specify a Content-Type, even if the response is encoded by contentType attribute of the Page directive. This is because there may be different Page directives specify the actual response of the region.
If the page contains I18N-capable format for setting the response behavior of the locale property (by calling ServletResponse.setLocale () method), set any encoding specified in the page will be overwritten.
