问题描述（必填）

当通过 webdav 上传文件到驱动内时，如果文件过大（大约 2M就会触发），就会提示405 Method Not Allowed
已经使用代码测试，只更换了文件，大文件就会报错，小文件就会成功，测试代码如下：

import requests
from requests.auth import HTTPBasicAuth

# 配置信息
webdav_url = "http://服务地址/dav/115/%E5%85%B6%E4%BB%96/cherry-studio/cherry-studio.20250910101624.Mac-mini-3.local.mac.zip"
local_file_path = "/Users/ws/Documents/cherry-studio.20250910101823.Mac-mini-3.local.mac.zip"
username = "账号"
password = "密码"

# 读取本地文件
with open(local_file_path, 'rb') as f:
    file_data = f.read()

# 发送 PUT 请求上传
response = requests.put(
    webdav_url,
    data=file_data,
    auth=HTTPBasicAuth(username, password),
    headers={
        "Content-Type": "application/octet-stream"  # 或根据文件类型设置
    }
)

# 检查响应
if response.status_code in [200, 201, 204]:
    print("✅ 文件上传成功")
else:
    print(f"❌ 上传失败，状态码: {response.status_code}")
    print(response.text)

The issue names no source files or tests. Start by reproducing a PUT upload larger than about 2 MB through /dav/115 using the supplied Python request, then trace the WebDAV upload handling and 405 response. Done means large files upload successfully while the existing small-file behavior remains intact.
