How can I fix this issue?
P.S.
I already installed GWT Developer plugin for Firefox 1.23

I was facing the same issue , you can try this if you are getting this problem -

I am using mod_security with CRS 3.3.0 on top of Apache 2.4. During a recent L7 DDoS attack, I recognized that certain attacks using HTTP/1.* were correctly block with HTTP 403 based on geolookup and having the country code listed in tx.high_risk_country_codes of the CRS config. However, a request from the identical IP was not blocked when using HTTP/2 as protocol. Any idea of a configuration setting specific for REQUEST-910-IP-REPUTATION.conf only enabled for protocols HTTP/1.* in the default rule set? For the time being, I restricted allowed protocols to HTTP 1.1 for affected site make mod_security working.
Some examples from access log:
<HOST>:443 XXX.XXX.XXX.XXX - - [03/Aug/2022:00:37:49 +0200] "GET /?s HTTP/1.1" 403 5636 "https://<HOST>/?s" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.84 Safari/537.36"

Thanks in advance!
SCHAPPY
CRS dev-on-duty here. There is no configuration setting specific for REQUEST-910-IP-REPUTATION.conf that is only enabled for protocols HTTP/1.*.
I have no idea why the rule 910100 does not work for HTTP/2.
But do you have the possibility to enable debug logs (better not in production) with SecDebugLog and SecDebugLogLevel? Maybe you'll get more insights this way?
If you can't see and solve the problem with the modsec_debug.log, you can open an issue in the Core Rule Set GitHub project. We're happy to help!
This is my Gatling http configuration
val httpConf = http
.maxConnectionsPerHostLikeChrome
.baseUrl(BASE_URL)
.inferHtmlResources(BlackList, WhiteList(BASE_URL+"/*"))
.headers(headers)
.userAgentHeader("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36")
.disableCaching
The inferHtmlResources usage here is throwing an error
found : String
required: io.gatling.core.session.Session
.inferHtmlResources(BlackList, WhiteList(BASE_URL+"/*"))

My code seems to be inline with the gatling documentation here
My Gatling Version is 3.4.2
Java JDK11

Can anyone point me why I am getting this error and how can I fix this. Thank you.
I'm trying to get JSF 2.2 to run on GAE 1.8.7. I'm following this tutorial: http://java.wildstartech.com/Java-Platform-Enterprise-Edition/JavaServer-Faces/javaserver-faces-22/configuring-jsf-22-to-run-on-the-google-app-engine-using-eclipse
When I run it locally, then the index.jsf page renders well.
However, when I deploy it to GAE, while normal servlets run well, the index.jsf shows a HTTP 505 error with the following in the GAE logs:
2013-11-15 11:23:42.578 /index.jsf 500 533ms 0kb Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.57 Safari/537.36 module=default version=1 W

at com.sun.el.lang.Evalua
I'm using javax-faces.2.2.0.jar and javax-el.3.0.0.jar from maven repository.
If you don't really need the EL 3.x features, then I would suggest moving to a 2.x version and then specifying it in your web.xml file as a context parameter:
<context-param>
<param-name>com.sun.faces.expressionFactory</param-name>
<param-value>com.sun.el.ExpressionFactoryImpl</param-value>
</context-param>
The above declaration will ensure that you are using the EL version that is shipped along with your code and not the one provided by the GAE/J container.
Don't forget to include the EL implementation jar as well in your libraries.
p.s.: If it is of any help, I have a starter template on GitHub that can help you get started.
I have build it from eclipse and ran on development server, it works, when I deploy it on app engine from eclipse, I got this following error, any idea why?
Very first time it went up to oauth2 dance, but it did not succeed, I have fixed redirect-url on api console, then, localhost worked, I did deployed again onto app engine, but it did not work, I got this error:
Error: 500 Server Error
The server encountered an error and could not complete your request.
If the problem persists, please report your problem and mention this error message and the query that caused it.

This looks like a bug in App Engine and the Google OAuth endpoints. It's being tracked in the Glass issue tracker. You can star that issue to receive updates as the investigation proceeds.
In the mean time, check out the .NET and PHP quick starts. They're working great.
I would like to ask what are the differences between the development server and the production server.
To be more specific, I give an example, I can run my application in the development server but when deploy to the production server, there is an error
500 Internal Server Error
So, can you please give me some advices?

It is so strange that it gave me the message, "no module named tools", as I copied the code of uploading data from google
In the development server, it works :-s
