URL Snooper


URL Snooper is a program written to help users locate the urls of audio and video files so that they can be recorded. Many links to streaming audio and video that you come across on the web are hidden behind javascript or activex scripts. Because of this, it is sometimes very difficult to figure out the actual urls that correspond to the streams being played. URL Snooper provides easy solution to finding the URLs for all streams by by watching network traffic and identifying potential urls, especially streaming media urls.

Complete Version history / Release notes / Changelog

2.41.01 - Mar 24, 2017

[MajorFeature] First High-dpi compatible version beta.
[Bugfix] Minor UI bugfixes.
[Improvement] Better mouseover hints for General Options.
[MinorFeature] New option to not clean/truncate displayed urls.

2.39.01 - Nov 6, 2015

[BugFix] Custom application links could sometimes drop surrounding quotes (thanks Quaraxkad).

2.38.01 - Apr 28, 2015

[Feature] New option to start sniffing immediately when program is started, even in advanced mode.
[BugFix/Feature] New option to better handle the "Also Find" text. In previous versions a url would be excluded if it did not match url filter type (multimedia vs all), even if it contained an Also Find keyword. You now have an option (enabled by default) to always include results that match the Also Find keyword, even if it does not match the url filter type. This is most useful when restricting search for multimedia urls but also anything containing the keyword. Tip: Use ; character to separate multiple keywords.

v2.37.01 - Dec 31, 2014

[Feature] Added new option to capture a few packets subsequent to any triggered capture, to help see what information came after the triggered capture.
[Feature] Larger block of data is saved around found urls.
[MinorFeature] Ctrl+A to select all urls in view.
[MinorFeature] Added quick forum link to help menu.
[MinorChange] Removed "minimize-to-tray" captionbar button.
[BugFix] Mixed rare mystery exception crash on sniffing.
[BugFix] Removed rare error report of "too small packetmem"
[BugFix] File search dialog was malformed; program hung if you didn't specify files to search for.

2.35.01 - July 14, 2014

[MinorFeature] New export option to export all columns of result table

2.34.01 - May 19, 2014

[BugFix] Some adapters were shown with same name in adapter list -- adapters are now shown with more descriptive names.
[BugFix] UrlSnooper was failing to sniff from some adapters (when those adapters were shown with identical generic names in list).

2.33.01 - Nov 28, 2013
[MinorChange] Better formatting for timestamp column.
[Feature] When scanning files (instead of network traffic), the filename is now shown in SourceIP column.
[WinPcap] Now distributed with WinPcap v.4.13
[Feature] Option to check for updates at startup.

2.32.01 - Feb 4, 2013

[Feature] SMTP multimedia links were not shown when multimedia protocol filter was enabled.
[MinorChange] Improved text labels for search filters.
[MinorChange] Changed auto network adapter test url and search string
[BugFix] An error about "Scrollbar property out of range" could be generated when resizing raw packet view panel.
[BugFix] Parentheses in urls were truncating urls at that point.
[Feature] View Live Packets option is now on main window and easily toggles live packet panel (size is remembered)
[Feature] Added datetime column to url grid.
[Documentation] Updated documentation with some links to a few popular downloader tools.
[Feature] Portable zip now uses ConfigDir_Default.ini which is overridden by the presence of a ConfigDir.ini file, so users unpacking the contents won't overwrite any custom ConfigDir.ini they may have.

Version 2.26.01 - December 13, 2009

[BugFix] Improved detection of network adapters -- was failing to list all available adapters on some people's computers.Thanks to ixxo and everyone else on dc forum who reported and helped test (see here for the thread).

Version 2.22.01 - June. 4, 2008

* Fixed language translation files.
* Increased max URLS that can be kept at once.
* New option to discard filtered-out urls that aren't display; normally the program stores all urls found even if its currently set to filter out all but multimedia urls, so that you can change the view filter to show all urls after the fact.The new option will discard them during filtering, which is a good solution for people who were ending up storing huge numbers of urls while searching for multimedia urls.
* Hopefully fixed "Menu - Index out of range" error.
* Removed some code to reassemble packets (it's possible this could result in worse url grabbing in rare cases -- stay tuned).
* Upgraded to winpcap 4.1beta4.

Review by URL Snooper on May 25, 2019 Version: 2.42.01 OS: Windows 10 64-bit Ease of use: 10/10 Functionality: 10/10 Value for money: 10/10 Overall: 10/10

You have a link to "portable".

Although there is a valid link - this program is not portable as it requires WinPcap to run. WinPcap has no portable version - installs a drivers(s) to intercept and interpret the url.

The rating is more for videohelp than for the app (as it is a required field).

Review by ricksterto on Sep 18, 2014 Version: 2.36.01 OS: Windows 7 64-bit Ease of use: -/10 Functionality: -/10 Value for money: -/10 Overall: 5/10

This is a great little tool if you don't want to have to watch the whole file on a web page, you can just download the flash that you want, it finds all of the associations with a page, your video is easy to spot. I did it very quickly just manually adding the main address, it broke it down into all of the components, then easy cheesy, just downloaded a 79Mb video that I wanted in about 15 minutes. The only drawback is the elaborate license key retrieval, but then they want to make sure you know where and who to donate to for this spiffy little prog if you are so inclined. I find it very well done and will be sending a few bucks for the cause.
