通过设置Pragma：无缓存

在我的情况下，我用这个解决了chrome中的问题

<form id="form1" runat="server" autocomplete="off">

当用户出于安全原因单击“返回”按钮时，我需要清除先前表单数据的内容

将修改后的http头设置为1995年的某个日期通常会起作用。

下面是一个示例：

Expires: Wed, 15 Nov 1995 04:58:08 GMT
Last-Modified: Wed, 15 Nov 1995 04:58:08 GMT
Cache-Control: no-cache, must-revalidate

对于ASP.NET Core，创建一个简单的中间件类：

public class NoCacheMiddleware
{
    private readonly RequestDelegate m_next;

    public NoCacheMiddleware( RequestDelegate next )
    {
        m_next = next;
    }

    public async Task Invoke( HttpContext httpContext )
    {
        httpContext.Response.OnStarting( ( state ) =>
        {
            // ref: http://stackoverflow.com/questions/49547/making-sure-a-web-page-is-not-cached-across-all-browsers
            httpContext.Response.Headers.Append( "Cache-Control", "no-cache, no-store, must-revalidate" );
            httpContext.Response.Headers.Append( "Pragma", "no-cache" );
            httpContext.Response.Headers.Append( "Expires", "0" );
            return Task.FromResult( 0 );
        }, null );

        await m_next.Invoke( httpContext );
    }
}

然后在Startup.cs中注册

app.UseMiddleware<NoCacheMiddleware>();

确保在以下位置添加此

app.UseStaticFiles();

完成BalusC->答案如果您使用的是perl，则可以使用CGI添加HTTP标头。

使用Perl：

Use CGI;    
sub set_new_query() {
        binmode STDOUT, ":utf8";
        die if defined $query;
        $query = CGI->new();
        print $query->header(
                        -expires       => 'Sat, 26 Jul 1997 05:00:00 GMT',
                        -Pragma        => 'no-cache',
                        -Cache_Control => join(', ', qw(
                                            private
                                            no-cache
                                            no-store
                                            must-revalidate
                                            max-age=0
                                            pre-check=0
                                            post-check=0 
                                           ))
        );
    }

使用apachehttpd.conf

<FilesMatch "\.(html|htm|js|css|pl)$">
FileETag None
<ifModule mod_headers.c>
Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
</ifModule>

注意：当我尝试使用html META时，浏览器忽略了它们并缓存了页面。

我在＜head＞＜meta＞元素方面运气不佳。直接（在HTML文档之外）添加与HTTP缓存相关的参数确实对我有用。

Python中使用web.py-web.header调用的示例代码如下。我有目的地编辑了我个人无关的实用程序代码。

    import web
    import sys
    import PERSONAL-UTILITIES

    myname = "main.py"

    urls = (
        '/', 'main_class'
    )

    main = web.application(urls, globals())

    render = web.template.render("templates/", base="layout", cache=False)

    class main_class(object):
        def GET(self):
            web.header("Cache-control","no-cache, no-store, must-revalidate")
            web.header("Pragma", "no-cache")
            web.header("Expires", "0")
            return render.main_form()

        def POST(self):
            msg = "POSTed:"
            form = web.input(function = None)
            web.header("Cache-control","no-cache, no-store, must-revalidate")
            web.header("Pragma", "no-cache")
            web.header("Expires", "0")
            return render.index_laid_out(greeting = msg + form.function)

    if __name__ == "__main__":
        nargs = len(sys.argv)
        # Ensure that there are enough arguments after python program name
        if nargs != 2:
            LOG-AND-DIE("%s: Command line error, nargs=%s, should be 2", myname, nargs)
        # Make sure that the TCP port number is numeric
        try:
            tcp_port = int(sys.argv[1])
        except Exception as e:
            LOG-AND-DIE ("%s: tcp_port = int(%s) failed (not an integer)", myname, sys.argv[1])
        # All is well!
        JUST-LOG("%s: Running on port %d", myname, tcp_port)
        web.httpserver.runsimple(main.wsgifunc(), ("localhost", tcp_port))
        main.run()
