+
+```http://localhost:8888/api/http/alloc_info```
+
+## Purpose
+
+Request a JSON encoded sub-list of allocation descriptors from the Memory Manager’s alloc_info list.
+
+## Query String Parameters
+| Parameter|Default|Description                       |
+|-------------|----|----------------------------------|
+| ```start``` | 0  | starting index of the sub-list.  |
+| ```count``` | 20 | number of allocation descriptors.|
+
+### EXAMPLE:
+
+```http://localhost:8888/api/http/alloc_info?start=20&count=2```
+
+## Query Response
+
+Returns a JSON object containing four name-value pairs:

+
+| Name              | Value Description                       |
+|-------------------|-----------------------------------------|
+| ```alloc_total``` | Total number allocations in the Memory Manager’s alloc_info list. |
+| ```chunk_size```  | Number of allocation description objects in ```alloc_list```. |
+| ```chunk_start``` | The Memory Manager alloc_info index of the first ```alloc_list``` element below|
+| ```alloc_list```  | Array of JSON Allocation Description objects (described below). |
+
+
+### JSON Allocation Description Object
+
+| Name          | Value Description                                                               |

+## Example:
+
+In ```SIM_cannon_numeric``` (one of Trick's example sims) the following query resulted in the following JSON.
