Proposal: /NOIEPROXY flag for nsisdl plugin
Hi,

I've just made a little modification to nsisdl: I've introduced a new flag called /NOIEPROXY which makes the plugin not to read IE proxy settings, so it tries to download the files directly.
The reason behind this modification is that in certain enviroments, some of the intranet http servers can't be connected via the corporate proxy server and I can't make the users switch to M$IE proxy options just because that single download, it's easier to give them the option to not to use the proxy in that one case.
Use:

The /NOIEPROXY flag should be the first flag for the nsis::download command.
If /NOIEPROXY or /NOIEPROXY=1 is the first flag for this command, then the IE proxy config is not used. Examples:

• NSISdl::download /NOIEPROXY http://www.domain.com/file localfile.exe
• NSISdl::download /NOIEPROXY=1 http://www.domain.com/file localfile.exe

• NSISdl::download http://www.domain.com/file localfile.exe
• NSISdl::download /NOIEPROXY=0 http://www.domain.com/file localfile.exe

Well, I though this topic generates much more interest than that :)
Anyone interested?

Hi Marc,

I forgot to mention, and that might disturb people: If you apply the patch against nsisdl.cpp in the NSISDL source, you'll get the modified source.

The directory where the cpp file to be patched resides is:

C:\Program Files\NSIS\Contrib\NSISdl

/usr/bin/patch nsisdl.cpp nsisdl.cpp.diff.txt

confused...
1. do I add the /NOIEPROXY flag to nsisdl.cpp (where?)?
2. what about deleting nsisdl.dll file if my installer has no need to go to any webserver? Is that a working solution?

Hi mdm,

1: you have to patch your nsisdl.cpp the way I described above. I'll attach to whole source, in case you don't have patch utility. Usage is described in my first post: you have to put this flag right after the 'NSISdl::download' command.
2: Well, I'm not sure if I understand what you mean to say. My patch is to enable an NSIS user to avoid to use MSIE's web proxy settings and go to the web server directly. If your installer does not download data via web, you just simply comment out the 'NSISdl::download' command in your script.

please excuse me for being obtuse here..
my nsisdl.cpp and the one you sent has no line: NSISdl::download.
Is NSISdl::download a command for my nullsoft installation script? I don't have any web downloads within my installation script("If your installer does not download data via web, you just simply comment out the 'NSISdl::download' command in your script").

appreciate your patience,
mdm

Mdm,

'NSISdl::download' is invocation form of "NSISdl" plugin's "download" function, so in this form it should present in an nsi script, so "C:\Program Files\NSIS\Contrib\NSISdl\ReadMe.txt" for details. If you don't want to use web in your NSIS installer you, don't need it and this topic is needles either :)
In the nsisdl.cpp you can find a line starting with "_declspec(dllexport) void download", that's where you can check the C++ source code.

Memph

Modified nsisdl.dll
Could you please upload the recompiled nsisdl.dll with the /NOIEPROXY flag?

I would be much obliged
