HTTPREPLAY is a SOCKTRC plugin allowing to analyze and replay HTTP traffic from STRACE or WININET log. You can use this tool to "replay a web server" without needing to setup IIS. The main goal of this tool is to help building a repro scenario when customer can't provide one.

Additional Information
· HTTPREPLAY reads the log file using a single ReadFile operation. Therefore, the size of the LOG must match your memory configuration.

· it is recommended to replay a trace on a machine using similar IE version & settings than the one used for the trace. In particular, ensure IE is using the same HTTP version on the replay box than the one where the trace was done.

· you may consider using HTTP 1.0 to avoid dealing with HTTP compression and easily be able to search/modify data in *.replay files. You can also use the BUILDCONTENT.CMD command to retrieve uncompressed content from index.replay.

· HTTPREPLAY first tries to sends back the largest HTTP 200 OK response found. If such response is not available, the tool will send back the first response found for the URL requested. This method allows to replay HTTP traffic even if 401 or 407 responses are used.

· HTTPREPLAY is now able to replay STRACE log containing SSL (HTTPS) traffic. For example, you can get an STRACE log for HTTPS://WWW.VERISIGN.COM and you'll subsequently be able to replay it using HTTP. The tool will automatically convert HTTPS urls in pages to HTTP. STRACE logs for the following HTTPS web sites were successfully tested : OWA, Hotmail, Verisign, HSBC
