377326 - File upload over SSL blocks any other SSL requests to the same server.

Status: VERIFIED WORKSFORME

(Core :: General, defect)

Description

[Motoma]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3

When uploading a file via a web form using POST over HTTPS, no other SSL requests go through until the file upload is complete.

Reproducible: Always

Steps to Reproduce:
1. Create a web form with a file upload (INPUT TYPE=FILE) using the POST method (ACTION=POST) and a submit button.
2. Access the page via HTTPS and upload a larger file.
3. Open a new tab and try to connect to the same server using HTTPS.

Actual Results:  
The page will not load until the file upload has completed or ended.

Expected Results:  
The page should load regardless of a file upload.

This is preventing AJAX scripts from running while users upload files. It prevents file upload monitoring while using HTTPS. Scripts which work using HTTP do not work using HTTPS.

-> Core for triage.

Motoma: Is this still an issue ? 
This seems to work fine with a current Firefox build.

No, I am no longer able to reproduce this issue, it must have been fixed sometime in the past 7 years.

I have reproduced this bug

GWT project files - compiled to JavaScript
form method=POST action=/relative/url/path
file size 900MB by reproduced this bug with smaller files
server connection is HTTPS

Copied all network traffic as HAR, notice that after POST to /privatekey, there are no reponses -- all response status codes are 0
