 # Web Page Replay
 Web Page Replay (WprGo) is a performance testing tool written in Golang for
 recording and replaying web pages. WprGo is currently used in Telemetry for
 Chrome benchmarking purposes. This requires go 1.8 and above. This has not been
 tested with earlier versions of go. It is supported on Windows, MacOS and Linux.
 
 ## Required packages
 
 ```
 go get github.com/codegangsta/cli

   ```
   ...
 
   Ctrl-C
 
 * Terminal 2:
 
   ```
   google-chrome-beta --user-data-dir=$foo \
    --host-resolver-rules="MAP *:80 127.0.0.1:8080,MAP *:443 127.0.0.1:8081,EXCLUDE localhost"
-   --ignore-certificate-errors-spki-list=PhrPvGIaAMmd29hj8BCZOq096yj7uMpRNHpn5PDxI6I=
   ```
   ... wait for record servers to start
 
 ### Replay mode
 * Terminal 1:
 
   Start wpr in replay mode.
   ```
   go run src/wpr.go replay --http_port=8080 --https_port=8081 /tmp/archive.wprgo
   ```
 
 * Terminal 2:
   ```
   google-chrome-beta --user-data-dir=$bar \
-   --host-resolver-rules="MAP *:80 127.0.0.1:8080,MAP *:443 127.0.0.1:8081,EXCLUDE localhost"
-   --ignore-certificate-errors-spki-list=PhrPvGIaAMmd29hj8BCZOq096yj7uMpRNHpn5PDxI6I=
+   --host-resolver-rules="MAP *:80 127.0.0.1:8080,MAP *:443 127.0.0.1:8081,EXCLUDE localhost"`
   ```
   ... wait for replay servers to start
 
   load the page
 
 ## Running on Android
 
 You will need a Linux host machine and an android device.
 
 * Set up reverse port forwarding
 
 ```
 adb reverse tcp:8080 tcp:8080
 adb reverse tcp:8081 tcp:8081
 ```
 
 * Set up command line arguments
 
 ```
-build/android/adb_chrome_public_command_line --host-resolver-rules="MAP *:80 127.0.0.1:8080,MAP *:443 127.0.0.1:8081,EXCLUDE localhost" \
-  --ignore-certificate-errors-spki-list=PhrPvGIaAMmd29hj8BCZOq096yj7uMpRNHpn5PDxI6I=
+build/android/adb_chrome_public_command_line '--host-resolver-rules="MAP *:80 127.0.0.1:8080,MAP *:443 127.0.0.1:8081,EXCLUDE localhost"'
 ```
 
 * Run wpr.go as usual on the linux machine
 
-### (Optional) Installing test root CA
+### Installing test root CA
 
 WebPageReplay uses self signed certificates for Https requests. To make Chrome
-trust these certificates, you can use --ignore-certificate-errors-spki-list
-like above. If that doesn't work, you may try installing a test certificate
-authority as a local trust anchor. **Note:** Please do this with care because
-installing the test root CA compromises your machine. This is currently only
-supported on Linux and Android.
+trust these certificates, you can install a test certificate authority as a
+local trust anchor. **Note:** Please do this with care because installing the
+test root CA compromises your machine. This is currently only supported on
+Linux and Android.
 
 Installing the test CA. Specify a `--android_device_id` if you'd like to install
 the root CA on an android device.
 ```
 go run src/wpr.go installroot
 ```
 Uninstall the test CA. Specify a `--android_device_id` if you'd like to remove
 the root CA from an android device.
 
 ```
 go run src/wpr.go removeroot
 ```
 
 ## Other use cases
 
 ### Http-to-http2 proxy:
 
 * Terminal 1:
 ```
 go run src/wpr.go replay --https_port=8081 --https_to_http_port=8082 \
   /tmp/archive.wprgo
 ```
 
 * Terminal 2:
 ```
 google-chrome-beta --user-data-dir=$foo \
   --host-resolver-rules="MAP *:443 127.0.0.1:8081,EXCLUDE localhost" \
-  --ignore-certificate-errors-spki-list=PhrPvGIaAMmd29hj8BCZOq096yj7uMpRNHpn5PDxI6I= \
   --proxy-server=http=https://127.0.0.1:8082 \
   --trusted-spdy-proxy=127.0.0.1:8082
 ```
 
 ## Inspecting an archive
 
 httparchive.go is a convenient script to inspect a wprgo archive. Use `ls`,`cat`
 and `edit`. Options are available to specify request url host (`--host`) and
 path (`--full-path`).
 
 E.g.
 
 ```
 go run src/httparchive.go ls /tmp/archive.wprgo --host=example.com --full-path=/index.html
 ```
 
 ## Running unit tests
 Run all tests in a specific file.
 ```
 go test transformer_test.go transformer.go
 ```
 
 Run all tests in `webpagereplay` module.
 ```
 go test webpagereplay -run ''
 ```
