SC Notes: Details for StreamCatcher users
- StreamCatcher v22.214.171.124 for IIS 7 and later
URL rewriting has been fixed to work with IIS 7, IIS 7.5
and (very likely) IIS 8.
The symptom was that status 301 and status 302 redirects
led to an internal problem in IIS (connection reset) with no corresponding entry in the IIS log
nor the System Event Log. Only the StreamCatcher tracelog
showed the redirect request and response.
- StreamCatcher v126.96.36.199 coordinated with WebHub v2.182 and v3.182
Changes impact WebHub sites only.
Changes impact webrobots only.
When using short URLs with a non-blank command string for webrobots, WebHub now sends :0: or /0/ as a placeholder for
the surfer session number. That avoids trouble with some bots who were collapsing // to a single slash and thereby losing the meaning of all commands. On the incoming side, StreamCatcher accepts both // and /0/ from webrobots. If a webrobot comes in with a surfer session number and a non-blank command, then StreamCatcher issues a status 301 bounce to a URL that contains either :0: or /0/ depending on the configured URL delimiter.
It is now possible to coordinate all sitemap URLs, all canonical URLs, plus all WebHub JUMP URLs with precisely consistent syntax.
If any search engine is reporting "health issues" on your site, specifically frequent "disconnect" errors, and your http server logs show status 301 bounces for webrobots, then upgrading to this version of StreamCatcher plus WebHub v2.182+ is likely to help -- assuming that you go to the trouble of making sure that ALL links fed to the search engine are consistent.
Note that google webmaster tools provides a way to remove invalid URLs from its index, which can speed up any cleanup phase.
StreamCatcher WebSite configuration samples with rules for WebHub URLs are included with
the webhubdemos project. This project can be downloaded from the Download link of any WebHub demo. Configuration files are in the Live\scwebsites folder.
- StreamCatcher v188.8.131.52 fixes corner-case problem
If you were remapping static URLs for web robots and staying
within the same domain AND the name of the matching incoming URL
was exactly 10 characters long including the leading slash (e.g.
/qhelp.htm), then you might have noticed that your rule never fired. In that one case, you need this bug-fix upgrade version 184.108.40.206.
- StreamCatcher v1.9 adds cycling
It is now possible to use StreamCatcher to remap using a
Cycle token, which cycles through a series of replacement
values (e.g. 1, 2, 3 or aa, bb, cc...). This can be used
for load-balancing and for simplistic advertisement rotation.
Version 1.9 is a PAID upgrade, $89, upgrade in
- StreamCatcher v1.9 major update
This version supports modification of data heading to IIS logs according to powerful regex rules.
This version also includes a standalone console which
has all the features of the one which works in IIS 5 in a
web browser. The only difference is that, for security reasons, the SCConsole.exe must
be run on a computer with the StreamCatcher configuration files.
You can use SCConsole.exe on a development computer to
test all your filtering and logging rules, even if you
do not have IIS installed or active on that development
- StreamCatcher v220.127.116.11 is ready
The new features are documented in StreamCatcher's HLP file. One is the <Conditions_tag> which may be added to rules to limit the rule to either HTTP or HTTPS. The other new feature is that
the list of webrobots can be maintained in a separate file,
referenced from the master configuration file.
- StreamCatcher on VISTA
Thanks to John Correa, we have confirmed that StreamCatcher
works on Vista.
- StreamCatcher v18.104.22.168 fully compatible with WebHub v2.8x
- StreamCatcher v22.214.171.124 supports regex
StreamCatcher users can now enter remapping rules using classic syntax or using
- StreamCatcher v126.96.36.199
StreamCatcher v188.8.131.52 is ready for download, and the help files have been updated. The manual has not been modified. The latest feature makes it easier for ASP programmers to remap their obsolete URLs because the equal symbol is now allowed in more syntaxes.
- StreamCatcher v184.108.40.206, ok for IIS 6
StreamCatcher v220.127.116.11 is ready for download, and it is suitable for use with IIS6 on Win2003. The SCHelpWH.hlp file has been updated to include notes for IIS6 usage, and all the latest versions.
- Lingvo support added
Minor release adds support for optional lingvo at beginning of short URL, e.g. www.href.com/deu/hrefsite/menu where "deu" is the lingvo code.
Major new release, SecureLinks, is an
additional DLL for people who do not use WebHub and find
themselves in a compromised situation and need to urgently
make all links unique and spoof-proof. Available by
special order only.
- StreamCatcher v18.104.22.168 (security patch)
StreamCatcher v22.214.171.124 is available for immediate download. This is a recommended upgrade for security reasons.
- StreamCatcher v126.96.36.199 supports rewriting HTTP headers
StreamCatcher v188.8.131.52 posted. This version adds support for rewriting headers. Search help file for "rewriting headers" for new syntax.
- StreamCatcher v184.108.40.206 posted (for WebHub users)
StreamCatcher now forces leading dash before AppID when remapping for web robots, but not when bouncing web robots. This applies on servers running multiple AppIDs with UseProcessID=true.
- StreamCatcher v220.127.116.11 (free upgrade)
This is a free upgrade for registered users.
This version supports remapping from http to https, and fixes a fairly obscure problem involving browsable directories whose names started with the same characters as valid WebHub PageIDs within the default WebHub application for the domain.
If you're interested in forcing HTTPS, search for "HTTPS" in the newly posted help file for instructions. (You will receive the new help file when you run the new SCSetup.exe.)
- StreamCatcher usage on Win2003
We have confirmed that StreamCatcher (as-is) works on Win2003 IIS 6 in "IIS 5 compatibility mode" and that it works in regular "worker process isolation mode" as long as you do not enable the Bytes Transferred report. Is anyone outside HREF using this report? We do not know. In any case, research has shown that the popular books on IIS are WRONG and that many things are still possible with filters that are documented as being impossible. So there you go.
