What is SAZ

SAZ‍ is a file format suffixed with .SAZ. SAZ is an abbreviation of Session Archive Zip. The SAZ file is used to store information for HTTP requests. The Fiddler software uses the SAZ format to save and read HTTP request information.

Save

On Fiddler, use the menu “File”>“Save” to save the current HTTP request information as a SAZ file. For ordinary users, if you encounter problems, you can use FiddlerCap software to intercept the information at the time of the error and save it in SAZ format and send it to the expert for analysis and processing.

Read

On Fiddler, use the menu <;file”>“load file" to read the SAZ file and load the HTTP request information.

Password Protection & zwj;

SAZ format files can be encrypted and protected using standard ZIP encryption, which is weak but fast. AES256 encryption can also be used, which is strong but slow. To enable AES256 encryption, you can enable it in the following menu: Tools > Fiddler Options > General.

To encrypt and protect the SAZ file, in the “Save Session File” dialog box, select “Copy-protected SAZ” in the “Save as type” drop-down box.

File Content

A SAZ file is a special format .ZIP file. You can change the .SAZ suffix to .ZIP and open it using the standard ZIP compression tool.

In the SAZ file, you can find:

1. _index.htm : An optional file for easy reading by the user. This file will not be processed when the SAZ file is loaded, only for manual checking.

2.raw folder: contains all the files that record the network Sesison information.

In the raw folder, there are three files for each network Sesison:

sessid#_c.txt: contains client requests

sessid#_s.txt : Contains server-side requests

sessid#_m.txt: Contains some metadata, such as: Session flag, socket reuse information, and so on.
