问题描述（必填）
If-Match, If-None-Match, ETag等使用可以有效避免文件被多个进程争抢覆盖（乐观锁）。目前openlist的webdav服务器实现上不符合 RFC9110 section-13.1.1和RFC9110 section-8.8.3，在不应覆盖文件的情况下错误的覆盖了文件。同时返回201 Created
下面是测试结果（以下为AI生成）：
条件写入测试结果
| 测试 | 正确行为 | 实际行为 | 结果 |
|---|---|---|---|
创建不存在的随机文件，If-None-Match: * |
创建成功 | 201，创建成功 |
正常 |
文件已存在，If-None-Match: * |
412，不得覆盖 |
201，内容被覆盖 |
错误 |
If-None-Match: 当前 ETag |
412，不得覆盖 |
201，内容被覆盖 |
错误 |
If-Match: 错误 ETag |
412，不得覆盖 |
201，内容被覆盖 |
错误 |
If-Match: 当前 ETag |
更新成功 | 201，内容更新 |
条件无法证明生效 |
If-Match: 过期 ETag |
412，不得覆盖 |
201，内容被覆盖 |
错误 |
| 覆盖已有文件时的状态码 | 200 或 204 |
始终返回 201 Created |
错误 |
此外，文件修改后 ETag 仍然一致，强 ETag 相同应当表示两个资源表示逐字节相同。在ETag的实现上也存在问题。
