Administrators • [SOLVED] Browser sends a JSON with a content-type of XML

My version is Release 9.0.0_ZEXTRAS_20221203.RHEL7_64_20221216110457 RHEL7_64 FOSS edition.

Our IT notifies me that users are sending lots of requests where the content-type header (XML) doesn't match the body (JSON) sent to Zimbra.
To be more specific

• The request was sent to "https://192.168.1.1/service/soap/NoOpRequest"
  This case is also found at
  https://192.168.1.1/service/soap/AutoCompleteRequest
  https://192.168.1.1/service/soap/SaveDraftRequest
  and other similar SOAP pages. (192.168.1.1 is the IP of our Zimbra server.)

• Content-type in the request header was

  Code:

  application/soap+xml; charset=utf-8

• Sample request body

  Code:

  {  "Header": {    "context": {      "_jsns": "urn:zimbra",      "userAgent": {        "name": "ZimbraWebClient - FF122 (Win)",        "version": "9.0.0_ZEXTRAS_20221203"      },      "session": {        "_content": 122,        "id": 122      },      "notify": {        "seq": 2      },      "account": {        "_content": "user1@demo.com",        "by": "name"      },      "csrfToken": "0_a2f2f......"    }  },  "Body": {    "NoOpRequest": {      "_jsns": "urn:zimbraMail"    }  }}

• This issue is seen only in the request header, and content-type in the response header seems to be correct.

As shown above, the body sent was a JSON, but the request header said it was an XML.
Such mismatches will be blocked by a WAF, and our IT refuses to whitelist them.
Their proposed solutions include changing request body to an XML or changing the content-type header as JSON.
So I'm looking for a way to achieve one of the solutions.
