909679 - Spaces in URIs get converted to %2520

Status: UNCONFIRMED

(Core :: DOM: Navigation, defect)

Description

[Helge Skjeveland]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:23.0) Gecko/20100101 Firefox/23.0 (Beta/Release)
Build ID: 20130814063812

Steps to reproduce:

Put up a Web object like test.pdf that has a clickable object in it whose URI contains a space (%20), like test%20me.mp3, the clickable object referenced in an HTML link, e.g. <a href="http://site/test.pdf:"></a>.


Actual results:

FF will not find the clicked object (404 error), because the %20 in its URI is double-escaped to %2520 when passed. I.e., the percent sign is converted to %25, and then 20 is added to it, generating a clobbered entity, disabling the passed URI.


Expected results:

The object should be loaded as encoded to the associated application in the O/S, with the space as %20 only.

See the URI http://www.bachware.com/Helge-music/The Lord's Prayer.pdf in which there is a link to http://www.bachware.com/Helge-music/The%20Lord's%20Prayer/The%20Lord's%20Prayer.mp3, but its %20s are converted to %2520s by FF 23.01 when the link pointing to it is clicked on, so the file is not found.  Looking at the .pdf file shows the code
/URI (http://www.bachware.com/Helge-music/The%20Lord's%20Prayer/The%20Lord's%20Prayer.mp3) where the%20s are being double-escaped to %2520s.

MSIE 10 passes the URI to the O/S correctly. So also does Opera 12.16.

The containing HTML page hash is http://bachware.com/Helge-music/Scores.htm#LP, where works OK the directly linked
<a The%20Lord's%20Prayer/The%20Lord's%20Prayer.mp3"
title="Click to play &ldquo;The Lord's Prayer&rdquo;&copy;">
<img src="../Graphics/TCLEFICO.GIF"
style="vertical-align: bottom;"></a>
that calls it, also in the link in the later page, http://bachware.com/Helge-music/The%20Lord%27s%20Prayer/systems.htm.

The problem is with a URI that calls an embedded object, in this case the pdf, that invokes the object whose URI has spaces. FF isn't passing on the spaces as specified, but double-escaping them, whereas MSIE and Opera do it correctly, and start the associated application.

When clicking on the embedded .mp3 link, FF reports:

The requested URI /Helge-music/The%20Lord's%20Prayer/The%20Lord's%20Prayer.mp3 was not found on this server.

But the address line shows the URI as
http://www.bachware.com/Helge-music/The%2520Lord%27s%2520Prayer/The%2520Lord%27s%2520Prayer.mp3

This indicates that the URI was received properly by FF, but was clobbered internally, as described.

This is still on prod.
All "%" in urls are replace by "%25"
And there is also all " " replace by "%2520" instead of "%20".
