Improved version of STRACE and HTTPREPLAY

  • Article

New version of STRACE and HTTPREPLAY have been posted on Microsoft's download center :

In addition to a couple of fixes, the following features have been added to HTTPREPLAY :

  • Fiddler (https://www.fiddlertool.com/fiddler/) traces can be replayed
  • both HTTP requests and responses are extracted from a STRACE log (/XTRACT switch)
  • the SENDFILE utility provided can be used to replay a request (like, for example, a large POST request)
  • new flag (/D:port /H:host ) can be used to route unresolvable requests to a specific host/post

When used with latest version of STRACE, HTTPREPLAY can also detect transport related issue (ex : TCP RESET upon send/receive). Such issues will be highlighted in the HTTPREPLAY report :
