Alert traffic

Alert traffic
Alert downloads can include a .wav or logo file. The alert is downloaded as an XML file with a name such as 
DUA209999990.XML
. The alert file is stored in the user’s 
AppData\Local\
AtHoc
[edition]
 folder. If the alert includes audio, the .wav file is downloaded separately and stored in the 
ProgramData\
AtHoc
[edition]\wav 
folder if not already present on the user’s computer.
The following table shows the relationship between logo size and alert payload size.

The above values are close approximations of the actual network traffic. The values are the size of the response text or files at the user’s computer and do not consider compression or HTTPS.

 The discrepancy in number of bytes between a payload with no image and one with an image is due to the image appearing as a binary blob in four locations in the code that is downloaded. This is a known issue in the server code base for release 6.1.8.90 and earlier. Versions 7.0.0.1 and later do not have this issue.
