Problem with wasm.br files

So i managed to serve the compressed builds with the proper .htaccess files. But i get these errors in the console. And also this appears when the build runs.

 

Is the Content-Type of the response header of * .wasm.br set to application/wasm?

 

That's the problem! How can i add the content-type to apache2? I have added the .htaccess file that we can see in the webgl documentatio of unity. Thanks.

 

add line to .htaccess

AddType application/wasm .br

 

Is it all correct?

 

sorry, Clear all relevant AddType / AddEncoding / AddOutputFilterByType in .htaccess and try the following settings

AddEncoding br .br
AddType application/wasm .wasm
AddType application/octet-stream .data
AddType application/javascript .js
AddOutputFilterByType BROTLI_COMPRESS application/wasm
AddOutputFilterByType BROTLI_COMPRESS application/octet-stream
AddOutputFilterByType BROTLI_COMPRESS application/javascript

 

Do i need to have brotli module enabled in apache2 for these commands to work?

 

Sadly, it didn't work.

 

yes, you need mod_brotli module install.
https://nixcp.com/install-mod-brotli-apache/

 

So i did the process described. Do this just allow me to serve the brotli files or does it compress the compressed files again?

 

Even after trying this process with the .htaccess file that you provided, still the same error.

 

Also keep in mind that I got the 2021 beta version.

 

Try to make the content of .htaccess only the following two lines

AddEncoding br .br
AddType application/wasm .wasm

 

So i tried that and i get this error now. I know i am from http because i can see the changes faster from my server.

 

delete this lines?

AddType application/octet-stream .data
AddType application/javascript .js
AddOutputFilterByType BROTLI_COMPRESS application/wasm
AddOutputFilterByType BROTLI_COMPRESS application/octet-stream
AddOutputFilterByType BROTLI_COMPRESS application/javascript

 

So i see that i get the same error trying to serve brotli2021 and also gzip2020 files. In gzip2021 with the same .htaccess as gzip2020, it works perfectly.

 

Should i add this line to my mime.types?

 

application/brotli not necessary.

and append dot.
AddType appication/wasm wasm -> AddType application/wasm .wasm

 

Yeah sorry for that. I tried it now but again the same errors

 

without mime.type application/brotli i get this in mozilla

with mime.type application/brotli br i get this mozilla

 

Delete this line if it exists.

AddType application/brtoli .br

 

No this line doesnt exist in my .htaccess file
My .htaccess file now is set to the original that is in the documentation.

After many tries i still can not understand the problem. I make changes ,restart server , clear the cache and then check if anything happened. But it seems that there is no solution and it is a unity WebGL bug.

 

Maybe I found the cause.
In Firefox, br is not added to accept-encoding unless it is HTTPS, even if it is localhost.
So, please try it in an environment that can be accessed via HTTPS.
(For example, use ngrok or upload it to Github Pages)

 

In firefox i get these messages even if it is https. Again i remind you that gzip2021 works perfectly. The problem is with gzip2020 and brotli2021 compressed builds. Any thoughts?

 

Here is my website btw: https://www.instahome360.com/brottli2021/index.html

 

My .htaccess file only 2 lines.
Both Chrome and Firefox can be loaded.

 

Oh i see. I use aws ec2 servers connected with aws cloudfront. That's weird i guess...

 

I tried ec2.

httpd.conf <IfModule mime_module> ~ </IfModule> in add 2 lines

AddEncoding br .br
AddType application/wasm .wasm

Both Crome/Firefox success

 

Let's get back a little, and think what we need to define, and why.

Also look at the sample on the manual (I guess you already did)
https://docs.unity3d.com/Manual/webgl-server-configuration-code-samples.html

Without gzip/brotli, we have 4 types of files that needs to be defined:
application/octet-stream .data
application/wasm .wasm
application/javascript .js
application/octet-stream .symbols.json

The ".symbols.json" is not a must, as it's used for development, and in most configurations Unity won't generate it.

In most updated systems, the server would already know about gzip/brotli, and if it sees a file that ends with ".br" or ".gz" it'll automatically set it's content type as "application/brotli" or "application/gzip".

This is why the sample in the manual suggest to remove those types, as they might already be defined
RemoveType .gz
RemoveType .br
RemoveLanguage .br

Now when those types have been removed, we can set the content encoding - so the client will know to unpack them.
AddEncoding gzip .gz
AddEncoding br .br

And also set the content type of the 4 files
AddType application/octet-stream .data.gz
AddType application/wasm .wasm.gz
AddType application/javascript .js.gz
AddType application/octet-stream .symbols.json.gz
AddType application/octet-stream .data.br
AddType application/wasm .wasm.br
AddType application/javascript .js.br
AddType application/octet-stream .symbols.json.br

 

You can also ignore the existing encoding, and do something like:

Code (JavaScript):

1. AddType application/wasm wasm
2. AddType application/octet-stream .data.br
3. AddType application/wasm .wasm.br
4. AddType application/javascript .js.br
5.  
6. <IfModule headers_module>
7.   <FilesMatch ".(br)$">
8.     Header set Content-Encoding "br"
9.     Header append Vary Accept-Encoding
10.   </FilesMatch>
11.   <FilesMatch ".(data.br)$">
12.     Header set Content-Encoding "br"
13.     Header set Content-Type "application/octet-stream"
14.   </FilesMatch>
15.   <FilesMatch ".(js.br)$">
16.     Header set Content-Encoding "br"
17.     Header set Content-Type "application/javascript"
18.   </FilesMatch>
19.   <FilesMatch ".(wasm.br)$">
20.     Header set Content-Encoding "br"
21.     Header set Content-Type "application/wasm"
22.   </FilesMatch>
23. </IfModule>

 

Oh thank you for trying! So in apache i only got apache2.conf file for configurations and the ability to place .htaccess files. Should i add this code into the apache2.conf ?

 

Thank you for your analytical answer! So should i copy paste this code into an .htaccess file under the Build subfolder?

 

It should be in ".htaccess" file. yes.
You can also copy the sample from the manual

 

I've already copied that from the manual without any success.

 

you can try copy the content in my second comment, but I didn't test it

 

Should i change anything in my conf file in apache2?

 

Ubuntu ? Amazon Linux ? What O.S. ?

 

I observe that gzip files are red


And br files are color-less. Why is this happening?

 

Amazon Linux

 

YES! We made it! I can serve my brotli files with aws amazon linux 2 with these 2 liners in the httpd.conf file. But ... in apache2 with my ubuntu 18 server what should i add to make it work like this too?

 

What about gzip serving? Just uncommenting the gzip line that is already present?

 

If you try configurations for both brotli and gzip you will get problem with gzip. I added AddEncoding gzip .gz and i get error about missing encoding gzip

 

@Steven_Damian

Try it with
AddEncoding x-gzip .gz

 

Okay now it works! The file is loading! But i get this error:

 

AddType application/wasm .wasm
Do you have?

 

Yes. For the brotli it works perfectly. Should i add Addtype application/wasm .wasm .wasm.gz ?
