Remarks
The Cache-Control: no-transform
HTTP header instructs network caching applications not to modify the document.
The Cache-Control: no-transform
HTTP header prevents downstream proxy servers from changing any header values specified by the Content-Encoding
, Content-Range
, or Content-Type
headers (this includes the entity body). For example, it prevents proxies from converting GIF images to PNG.
As with other restrictions on caching, once SetNoTransforms is called, the Cache-Control: no-transform
HTTP header cannot be disabled through the HttpCachePolicy interface.
SetNoTransforms is introduced in the .NET Framework version 3.5. For more information, see Versions and Dependencies.
