Data Saver Proxy (DSP) is Forward Proxy, designed to help reduce data transfers over the network.
Generally data reduction strategies are accounted for on the server end.
However there are numbers of websites which are not attentive enough with reducing data, resulting in faster data usage accumulation.
As DSP is a forward proxy, any data returned (downloaded) from the server will be shrinked by DSP before it reaches your device.
With it, you will be able to browse more websites in low limit data plan, and potentially improve browsing speed when download speed is restricted in your network.
Some data reduction strategies DSP takes are listed in the tiles below.
Trim part of text which is not visible to the user to reduce the data size
Shrink size and drop quality of image to reduce data size
Apply compression to raw data to reduce data size
To reduce data, DSP has to intercept requests exchanged between client and server. This is done with "man-in-the-middle" (MITM) process.
The idea of MITM is to pretend to be the server to the client, and pretend to be the client to the server.
MITM is predominantly described as one form of "attack".
What DSP does is trim down data as much as possible while conserving the original content (excl dropping image quality).
We want to be very clear that we are not performing any activities which will be considered attack.
