How do I add(modify) response header from ant-media server??

[Kai]

Hi, support team.

My name is Kai.
Let me ask you about response header.

I configured web application in lighttpd using ant-media server.
I need to set COEP and COOP configuration in lighttpd, So I want to add crossorigin info in response header from ant-media server.
However I have no idea how to add them.

How can I modify response header??

Thanks,
Kai

Hi, support team.

 

Sorry for the continuous posting.

To put it simply, since we are building a Cross-Origin-Isolated site, in order to embed information from the cross-origin site (embed WebRTC video from Ant-Media), the following is in the response header from Ant-Media Server. I want to add.

COEP (Cross-Origin-Embeded-Policy): require-corp
CORP (Cross-Origin-Resource-Policy): cross-origin

Hi @Kai,
How are you!

We have CORS Filter as a stream security feature in Ant Media Server that you can refer to.
https://resources.antmedia.io/docs/stream-security

Please let me know if it's of some help.

Thank you

Hi, Mohit

Thank you for your reply.

But for my recognition, this is a filter when Ant Media Server receives a request, it doesn't change the reponse header when Ant Media Server returns a response.

I just want to add COEP and CORP information to the "response" from Ant Media as shown in the figure below.
How does this realize?

Hi @Kai,

How are you!

Thank you again for your detailed response.

I have discussed about these with the team internally and the Lead Developer is looking into it and we will write to you very soon.

Thank you for your kind understanding.

Please let me know if you have any necessary information.

@kai ,

I believe ant media and similar Java based softwares are built on top of tomcat. I will suggest looking for " response header modification in tomcat " on the web.

For example here is something of interest.

Hi @Kai,

Thank you for your follow ups.

We've made some quick research for that and it seems that we find the same the way as @Connessione recommends.

Thank you so much @Connessione 🙂

@Kai, Please try to use the example link to add header and let us know if you need further help.

Also,Thank you again @Connessione In order to show our appreciation, we would like to have virtual coffee with you 🙂  so May I send a Starbucks gift card to your email?

 

Thank you.

Hi, @Connessione and @Mohit.

I did tried, but it didn't work following below step ..
(WebRTC has disappeared from the menu. Probably this is due to an error in web.xml.

It seems that ResponseHeaderFilter cannot be read from the placed jar file.)


Honestly I don't know in detail about java servlet..
Could you help me ??Do you know what's wrong.

1. sudo apt update
2. sudo apt install default-jdk (sudo apt install openjdk-11-jdk)
3. export JAVA_HOME=$(readlink -f /usr/bin/javac | sed "s:/bin/javac::") export PATT=$PATH:$JAVA_HOME/bin
4. sudo apt install tomcat9
5. sudo systemctl status tomcat9
6. create response-header-filter.jar ↓
   1. cd ~/work
   2. git clone https://github.com/Hory314/response-header-filter
   3. sudo javac -classpath /usr/share/tomcat9/lib/servlet-api.jar ResponseHeaderFilter.java
   4. jar -cvf response-header-filter.jar *.class
7. sudo cp response-header-filter.jar /usr/local/antmedia/lib/
8. edit web.xml --> sudo vi /usr/local/antmedia/webapps/WebRTCAppEE/WEB-INF/web.xml
9. sudo systemctl restart antmedia
