Question

将生成的电子表格下载到浏览器时，我的同事在Websphere 8.5.5中获得以下跟踪。一些谷歌搜索显示这与称为＆＃34; WebDAV＆＃34;的东西有关，但我们只是试图下载电子表格。下载仍然成功，但我们不希望这种情况进入生产并使日志变得混乱（目前他在本地使用WAS工作）。

是否有人知道如何抑制此消息（因为该功能确实有效）或更好，如果有一些提供电子表格的方法根本不会触发它？

Answer 1

此错误不会影响性能。顺便说一句，要摆脱这个错误，试试

1.改变IHS的httpd.conf，如下所示

LoadModule rewrite_module modules/mod_rewrite.so 
 RewriteEngine On 
 RewriteCond %{REQUEST_METHOD} ^PROPFIND 
 RewriteRule .* - [F]

别忘了重启IHS

2.使用较新版本的lib编译代码，例如使用commons-io-1.4.jar，comons-fileupload-1.2.1.jar等

不支持PROPFIND WAS 8.5
