It is recommended to leave some small (5MB) the browser disk cache, browser can use this cache for caching SSL pages. If you browser has delete cache on exit option, use it. For speeding browsing use memory cache if you browser supports it (Netscape and Opera does, Microsoft not). The size of the memory cache depends on the amount of free RAM, but 1500 K is a good starting point even if your system only has 16Mb RAM.
Bug in browser.
Make proxy chain: browser -> Smart Cache -> Junkbuster. New version of
Junkbuster is called privoxy.
You do not need that. If you want to force offline mode, use -local switch.
Yes go ahead, SC is open source software. Place it in any archive, you can use my name/email for entry submission if you are not like to use own.
Yes, SC do not delete anything from it. Your browser will be still able to use your old cached things. New things will be written to Smart Cache (by itself) and also to your browser's cache (by browser).
Set nocaching * , generate_lastmod yes, pragma_no_cache 1 , quick_abort_min 0 , quick_abort_max 0
Set generate_lastmod yes , pragma_no_cache 1 , remove_pragma_no_cache yes , and first number in default_refresh_pattern to non-zero (avoids another Netscape bug). Using URL blocking, Section 5.6 is good idea also. If you are only one SC user, set cache_password_protected 1 and cache_private 1.
Because there are much faster! There is no Unicode conversion stuff, which is not needed.
quick_abort_min 0 quick_abort_max 0
The best I can think of is to specify in gc.cnf for each directory I want to keep forever (something like): urlmask url /99999999999.
No, you can distribute unmodified SC in any way you like [10], you can sell it, place it on your webpage, burn it on CD-ROMs, even with included commercial programs. If you are ISP its OK to place it on your "startup" CDs and its OK to run SC in business environments for making money. But if you redistribute SC, you must redistribute GPL License also. If you want to distributed a modified version of Smart Cache see GPL License for some details.
Yes, GPL allows to use it for ANY purpose. This is called freedom zero.
Yes, SC used the same file format under both OSes. Many users do this, just place cacheroot directory on FAT disk, seen by both OSes.
In OS/2 you can run it invisibly via detach java -norestart -ms1m scache. Scache can very easily (in all Windows versions, afaik) be started from a batch file, like so:
@echo off
javaw -cp . -ms1m scache [etc... etc....]
cls
A desktop shortcut to this batch file, with in the properties a "close-when-finished" setting, will with one mouse click activate the cache and let it run invisible in the background (if necessary, it can always be unloaded later from the Ctrl-Alt-Del dialog). If you put the same shortcut in the Startup folder, the cache will be silently started every time you bootup.
You may have set incorrect block_size in gc.cnf or treesize
program do not report actual bytes used, but just sums of files length. See Configuration of garbage collection,
Section 4.2
When using Smart Cache, WWW browser sends less requests than without it. If you want to get comparable numbers with other proxy caches set generate_lastmod no and you will see, how much "ratio" will be increased. This of course do not made your browsing faster.
You can run it from All Users startup. See also http://support.microsoft.com/default.aspx?scid=KB;en-us;q137890
or you can use Firedaemon
program or JNT.
Just delete it and cached files. It do not writes anything to system directories, registers or other strange places.
This is probably a very common Windows NT (maybe 95/98/00 too?) problem. This was reported by many users. You must report this program to your Software or Operation System Vendors.
SC do not needs it, Sun Java itself caches all DNS responses, see Java DNS caching bug/feature, Section 12.1.
You can set BindAddress (Setting the bindaddress, Section 9.10) to your local LAN IP address to prevent Internet users from doing this. Using Fail *your.local.lan* works also. But BindAddress is faster, safer and cleaner. You can look also on Proxy access control, Section 9.11.
Only if requested page has Last-Modified date. If pages has Etag, Smart Cache uses If-none-match.
Smart Cache will use it as Pragma: no-cache. If pragma_nocache is set to non-zero, expire will be ignored and removed from server response.
Jikes compiles faster, but faster is only execution of the compiler. Jikes do
not generate code which runs faster than code generated by javac. Jikes can be
downloaded from AlphaWorks IBM site for free.
Source code for Jikes is available also. Jikes is written in C++. Some
virtual machines has problems when running jikes compiled classes, using javac
is recommended.
If you want, try it and distribute native versions yourself. See Making native executable, Section 9.4
Yes there are, especially for Windows some of them are mentioned in Other off line browsing solutions, Section 1.4. Try some of them and find it yourself. Better or worse are relative terms. Use server which works the best for YOU.
gc.cnf for HPFS there is a suggested block size of 1024 for HPFS, but the sector size on HPFS is 512 byte and there is no sector-clustering (or with other words a cluster-size of 1) for HPFS.HPFS really uses 512 bytes long file blocks, but every (even empty) file uses also one sector (512 bytes) FNODE and directory entry (ignoring their size). Summary: HPFS uses 512+blocks*512 per file. Because Smart Cache can not handle this configuration, is better to use 1024 block_size.
No. Many people use this software on Windows platform. I do not use it and hardly will ever write software for running only on it. It was coded under OS/2, now I am coding that under Linux and use this on Windows, Mac, OS/2 and Linux.
GUI Java applications are a quite slow. At least on my 486/33 you will not
have too much fun with it. But non-GUI Java programs (Windows based people
often says console or DOS) are much faster than other interpreted languages
(such as Perl or Python). There are fast as many C
programs. See Proxy cache Benchmarks, Section
9.2
I will not do that, it is waste of my time. If you want C++ performance you can Making native executable, Section 9.4. In fact Java language is not so slow, some caches coded in C are slower than this. [11]
Sources are available, you can rewrite it yourself or pay someone to doing it for you. This is one of key benefits of Open Source Software model.
Some ppl are doing that. In worst case when both caches are working with the same directory at same time; some files will gets cached twice and some lost due to unsynchonized .cacheinfo writings. If only one scache writes into folder, it is 100% ok. If you do not plan to offline browse, these writing conflicts are okay. Who cares on leased line about if some HTMLs or GIFs are loaded twice, there are small in size. Better is chain them: filtering sc with -ro -> non filtering sc -> Internet.
