Ken44 Posted April 16, 2009 Share Posted April 16, 2009 Hi Sam Thanks for your reply to my question 6 months ago. :) I had to switch gzip compression off because a 500 Internal Server Error prevents spiders from crawling my site. I never did find the cause of the problem. Regards Ken Link to comment Share on other sites More sharing options...
spooks Posted April 16, 2009 Author Share Posted April 16, 2009 Sorry, I have many threads & I can't watch them all. I would suspect an error with the library function on your server, its not windows by any chance? Sam Remember, What you think I ment may not be what I thought I ment when I said it.

Ken44 Posted April 17, 2009 Share Posted April 17, 2009 Hi Sam. Thanks for the info. (No, it’s not Windows) I never thought the problem could be with my host. I will talk to them. Regards. Ken Link to comment Share on other sites More sharing options...

Jan Zonjee Posted May 24, 2009 Share Posted May 24, 2009 what's wrong with that? That you are cross-posting (and bumping). That is what's wrong. See our forum rules. Link to comment Share on other sites More sharing options...
♥altoid Posted June 27, 2009 Share Posted June 27, 2009 Every now and then I go mining through the osCommerce site looking for stuff like this. I wasn't aware what the GZip aspect could do. Enabling that and putting in Sam's code in the admin side made both sides much quicker. Thank you Sam!! I am not a professional webmaster or PHP coder by background or training but I will try to help as best I can. I remember what it was like when I first started with osC. It can be overwhelming. However, I strongly recommend considering hiring a professional for extensive site modifications, site cleaning, etc. There are several good pros here on osCommerce. Look around, you'll figure out who they are. Link to comment Share on other sites More sharing options...
spooks Posted August 30, 2009 Author Share Posted August 30, 2009 A side benefit of using compression that hasn't been pointed out before is bandwidth. ;) Thats to say the bandwidth used on each access is dramaticaly reduced, so if your hosting has a limit on bandwidth use, it will take a lot lot longer for you to use that up once you enable. :D Sam Remember, What you think I ment may not be what I thought I ment when I said it.

skipunda Posted October 7, 2009 Share Posted October 7, 2009 What level of compression (1-10) would you recommend Spooks? I have set mine to 5. Also, can I measure the CPU strain on server using the Load Average in order to get this number right for my server? I know I should use 'Top' really but guess this is the same sort of thing?

mr_absinthe Posted October 31, 2009 Share Posted October 31, 2009 Hi When I enable GZip and go here to test it. http://www.gidnetwork.com/tools/gzip-test.php However below this it also tells me that the Response Headers have changed from a status of HTTP/1.1 200 OK to HTTP/1.1 500 Internal Server Error Is this anything to worry about? Regards Ken. Hi Sam, I'm also experiencing the same error as above. - If I keep it "ON" in admin - ERROR - If I turn it "OFF" - no error, no compression - If I turn it "OFF" and add ob_start("ob_gzhandler"); - ERROR I was suspecting .htaccess but after loading vanilla .htaccess, I see no difference, still error with Gzip "ON". I have created test store - vanilla install on the same server and there is no error with compression "ON". Do you have any idea what might be causing the error?

mr_absinthe Posted October 31, 2009 Share Posted October 31, 2009 Speak to your host, sounds like a issue with gzip on your server. Thanks for your reply, but test store - clean osC installation on the very same server runs without issues and it is compressed with no erros...? I have two stores on the same server: /catalog/ - that is a copy of the live store - errors when gzip enabled /test/ - clean install 2.2rc2a - no errors and compressed Those two test sites share the same database. /catalog/ is heavily modified, is there particular part that could have been affected in the code thus the errors? They run on php 5.3.0. I've compared gzip_compression.php files in both - identical. The code (// if gzip_compression is enabled, start to buffer the output) in application_top.php is also identical.

All the command does is tell the server to enable compression for your pages, your other code is irrelavent, if it dont work its a server issue, perhaps it requires a different command format, Speak to your host.

mr_absinthe Posted November 2, 2009 Share Posted November 2, 2009 For all those having similar difficulties... It was caused by .user.ini and application_top.php - error reporting. To make it work as wanted, I had to keep this in .user.ini: display_errors = 1 error_reporting = 2 and change application_top.php to: // set the level of error reporting // error_reporting(E_ALL & ~E_NOTICE); error_reporting(0); Changing display_errors = 0 in .user.ini did not help nor was working when I removed it and kept only register_globals = 0 for example. No idea why it is must be done like this but it is working.... uff :sweating: Absinthe Original Liquor Store Link to comment Share on other sites More sharing options...
minipassat Posted December 4, 2009 Share Posted December 4, 2009 Hello, I have similar problems like yours. I got error messages when GZip is enabled; or Gzip is off but add the code "ob_start("ob_gzhandler");" as instructed by spooks. I am not sure if it's because of the OSC version. Here are the error messages: In godaddy and powweb hosting, OSC version is MS2, PHP version 4+ in IE6: blank page in IE7: Internal Server Error - Read The server encountered an internal error or misconfiguration and was unable to complete your request. Reference #3.96f6a9ce.1259895023.0 in Firefox 3.5.5 - tells me the unsupported compression method is used. However in Hostexcellence hosting, OSC version is RC2, PHP version 4+, GZip is enabled, the website is compressed and working fine! Do you or anyone know what might be wrong? Thank you very much!! Thanks for your reply, but test store - clean osC installation on the very same server runs without issues and it is compressed with no erros...? I have two stores on the same server: /catalog/ - that is a copy of the live store - errors when gzip enabled /test/ - clean install 2.2rc2a - no errors and compressed Those two test sites share the same database. /catalog/ is heavily modified, is there particular part that could have been affected in the code thus the errors?

spooks Posted December 5, 2009 Author Share Posted December 5, 2009 it sounds like there are problems with gzip on the server, the best place to ask is your host to confirm its fully functional.

minipassat Posted December 6, 2009 Share Posted December 6, 2009 Hi Sam, I actually checked with Powweb and they don't provide GZip for their platform. For Godaddy server, they told me to insert the following code in index.php: After review of the hosting account the script provided earlier needs to be added to the index.php for the compression to function. With compression enabled in the Admin of the OsCommerce software we are unable to assist if that has caused the site to go have issues. Add the following code to the very top of your Web pages above the DOCTYPE: <?php if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) ob_start("ob_gzhandler"); else ob_start(); ?> I placed the code in index.php or includes/application_top.php or sts_template.html but non of it worked. Any possible solution? Thank you! it sounds like there are problems with gzip on the server, the best place to ask is your host to confirm its fully functional.

minipassat Posted December 7, 2009 Share Posted December 7, 2009 okay, I did some search from the internet and someone shared that Godaddy doesn't support GZip, however Godaddy says they do support it. Since the store I have on HostExcellence hosting is GZip compatible and functioning well, so I decided to create a sub-folder there and throw all the files used in Godaddy into that folder just to test if it's the server issue. The answer is - when GZip is enabled in admin, the client side is NOT working. Therefore I think maybe my files are somehow causing the issue? Here is what I have: OSC Version: 2.2 MS2 major Installed Modules: Header Tags SEO, Additional Images, FEC (fast easy checkout), Ultimate SEO URLs Is any of these modules not causing any problem to GZip? Need help please!! Thank you very mcuh!! Link to comment Share on other sites More sharing options...
minipassat Posted December 7, 2009 Share Posted December 7, 2009 or is it possible the Big5 or Utf8 issue? Thanks. Link to comment Share on other sites More sharing options...
pete2007 Posted December 7, 2009 Share Posted December 7, 2009 There is a option in admin, so if you have that 'on' don`t apply this to the client side. This can be done for any php document. In application_top.php both on client side & admin, near the top, after <?php add: ob_start("ob_gzhandler"); Hi, My settings in admin >Configuration >GZip Compression, are currently set to; False & 5 What settings do you recommend? Shall I also add the code to application_top.php ? Thanks in advance! Link to comment Share on other sites More sharing options...

pete2007 Posted December 8, 2009 Share Posted December 8, 2009 Hi, I changed the setting in admin, then I added the code just after <?php To: store/osc/includes/application_top.php And: store/osc/admin/includes/application_top.php I now get the following error: Any suggestions what I may have done wrong?

minipassat Posted December 8, 2009 Share Posted December 8, 2009 Hi, please ignore my previous post. (sorry I don't think it'd let me delete from the froum). I found that Godaddy does supports Gzip for OSC. I reinstall the original OSC (both RC2a and MS2 version) files and the GZip works fine. So I think the error message must caused by the modules I used which conflict with GZip. I am new to PHP and the site is heavely modified, does any know that enabling GZip might conflict with any of the modules below and what to check or how to fix: Additional Images Header Tags SEO Ultimate SEO Fast and Easy Checkout STS3 (template) Sub-Category Description FAQ System Product Sort Related Products Discount Coupon Codes Tiny MCE (Disabled) FCK Editor Export to CSV Google Sitemap Thank you!!
