The new dfsmedia pipeline is implemented as a httphandler, using a pipeline in Sitecore. This pipeline is located in the DFS.Services.config file:
| Code Block | ||
|---|---|---|
| ||
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
<sitecore>
<pipelines>
<DFS.Services.DFSMedia>
<processor type="DFS.Services.Pipelines.DFSMedia.CheckSecurity, DFS.Services" />
<processor type="DFS.Services.Pipelines.DFSMedia.GetMediaFromCache, DFS.Services" />
<processor type="DFS.Services.Pipelines.DFSMedia.GetMediaPrerequisites, DFS.Services" />
<processor type="DFS.Services.Pipelines.DFSMedia.GetMediaFromDigizuite, DFS.Services" />
<processor type="DFS.Services.Pipelines.DFSMedia.ResizeImage, DFS.Services" />
<processor type="DFS.Services.Pipelines.DFSMedia.SaveToCache, DFS.Services" />
</DFS.Services.DFSMedia>
</pipelines>
</sitecore>
</configuration> |
Each step is explained as follows:
| Pipeline name | Description |
|---|---|
| DFS.Services.Pipelines.DFSMedia.CheckSecurity | This pipeline looks up the asset in the index using the context user. If the user does not have access, the asset is not returned and the pipeline is stopped. |
| DFS.Services.Pipelines.DFSMedia.GetMediaFromCache | This pipelines constructs a unique name based on the request and checks if the requested asset exists in the cache. |
| DFS.Services.Pipelines.DFSMedia.GetMediaPrerequisites | If the asset is not cached, it needs to be requested from Digizuite. This pipeline gets all the prerequisites for requiring the asset in Digizuite |
| DFS.Services.Pipelines.DFSMedia.GetMediaFromDigizuite | This pipeline executes the request towards Digizuite |
| DFS.Services.Pipelines.DFSMedia.ResizeImage | If a resize or #compres?? is requested, the bytes are processed here |
| DFS.Services.Pipelines.DFSMedia.SaveToCache | This pipeline saves the image to the cache |
