Hi,
Further tests have shown that just copying a vbhtml file with gulp (just gulp.src and gulp.dest) create the same problem. I can use gulp-header to add the utf8 bom, which solves the problem. It seems IIS needs the utf8 bom, and gulp strips this from files by default (as it is deemed unnecessary).
Although it is not a problem in octpack itself, it is probably usefull to investigate this further and fix it in the octopackjs gulp wrapper. Or at least document the issue and propose a nice solution.
To reproduce the problem doing the following should suffice:
return gulp.src('view.vbhtml')
.pipe(gulp.dest('./test/'));
If you see the problem there, try this:
Var header = require(‘gulp-header’),
return gulp.src(‘view.vbhtml’)
.pipe(header(‘’))
.pipe(gulp.dest(’./test/’));
To get the entire thing working, there’s some work still to be done. Right now, gulp-header will fail if the stream contains directories. I’ve forked the project, and sent a pull-request. We’re currently discussing the exact implementation but it will be accepted eventually, and a new release will be created.
The next problem is that we don’t want to add the bom to every file. Dll’s, resx, images, … shouldn’t have the bom. Currently it seems only vbhtml (and possibly cshtml) should have the bom. I tried creating 2 streams (one for vbhtml, one for all the rest) and merging these using event-stream. But, after merging the paths are not correct anymore and octopack fails because of none existing files.
I’ll discuss with the gulp-header owner if we can add an optional parameter to limit the file types where the bom should be added to, and in the meantime try to get the event-stream owners to fix the file paths in merged streams.
If you have any other suggestions, or if you think I’m going down the wrong path, please let me know 
Kind regards,
Ruben
