File download fails in firefox in azure app service with mounted file storage-CodePudding

This is my stack:

Azure App Service (P1V2 Plan)
Docker Container
php:7.4-apache base image
apache2 config not changed
php config not changed
Azure Storage Account "Standard", also tried "Premium"
AzureFile mapped into subdir of document root.

I try to download a 75 MB file directly with apache2.

It works with Chrome Browser, but doesn't work in Firefox and curl.

For testing I created two different files:

a 2 MB File works to download in Firefox. A 3 MB File doesn't work in Firefox.

The download of the 75 MB file works if I don't put it in the AzureFile directory but in another directory directly in the container.

It seems that the Azure Storage is responsible that the file can not be downloaded in Firefox and curl. But in Chrome it works for some reason.

Am I missing any configuration or is this usecase not supported? How can I fix the download, that it works on all plattforms?

Edit:

curl output:

curl http://example.com/install/TheSetup.exe --output TheSetup.exe

Firefox error:

Firefox is downloading a portion of the file but very soon the "Fehlgeschlagen" is appearing.

CodePudding user response：

This issue may happen depending on your Windows version security software stops the downloads and Firefox always uses the temp folder to start the download in the background so large files can't be able to download

If you are using extension, try to Disable or remove extensions via Tools -> Add-ons -> Extensions
Try to close the to close Firefox completely and delete the "compreg.dat" file from the Firefox profile folder
Otherwise, In new tab type about:config -> accept & continue and in that search box type browser. download in that you can see browser.Download.manager.ResumeOnWakeDelay change it as hundred thousand and browser.downloads.SaveLinkAsFilenameTimeout change it as 40 thousand and Enter may have possibilities to work

For downloading in curl try using below :

curl --location --request GET 'https://go.microsoft.com/fwlink/?linkid=2108834&Channel=Stable&language=en' --output foo.exe

CodePudding user response：

There are two configuration settings for network storage mounted directories like NFS or SMB that also apply for this usecase of azure storage mounted in azure app service docker container:

EnableSendfile Off
EnableMMAP Off

This can be set for the virtual host or per directory.
