gzip without server support?

I have written a css server which does minimization and basic parsing/var replacement. The server is using node.js. I am wanting to gzip my response from this server. As told in IRC, node.js does not currently have a gzip lib, so I am attempting to do it manually from the command line (as I am only gzipping when not in cache). I am pus...

Why is gzip compression not working?

This is an odd one. I am slowly rebuilding a website on a live server. Some sections of the site have been rebuilt and therefore the code is placed in a subdirectory of the home dir (ie:/mysite/newcode). I had successfully gzipped the old site using ob_start("ob_gzhandler"); So, i have applied the exact same code for the new code. Howe...

C http request gzip (zlib)

I'm making http requests using winsock and I need to parse the html. The problem is that some sites I'm working with compress the html in gzip no matter what I specify in my request header.

GZip compression on HTTP Request with Tomcat

I'm new to using Tomcat so perhaps I'm missing something. In the server.xml it looks as though it is possible to enable GZip compression for HTTP Responses from the server to the client.

Changing response type in aspx page breaks in IIS7

I have a custom implementation of Application_PreRequestHandlerExecute which is applying a deflate/gzip filter to the response. However, on IIS7, this is failing on my "script generator" pages. These aspx pages take in Query String values and return a custom bit of script, changing the response type to text/javascript. I think it is fail...

Ajax response is gzip compressed - Prototype, Firefox can't handle it

I'm trying to query a webservice (with javascript, prototype). The server responds with XML, but compresses it; headers are set appropriately. Under Safari 4, everything is fine. The response is decompressed and Javascript can deal with the data. Under FireFox 3.5.8, no data is returned to Javascript! Code: var req = new Ajax.Re...

Sending gzipped form data

I've heard how browsers can receive gzipped pages from the server. Can they also gzip form data that they send to the server? And if it's possible, how would I decompress this data on the server? I'm using AppEngine's webapp module, but a general explanation / pointers to tutorials would be sufficient. I've done some googling to no avai...

I know not combining the scripts is generally a less preferred approach, and I'm sure it's probably the way I wil...

Speeding up site using gzip and far-future expiration dates.

YSlow gives an A grade for Gzip but does not mention that gzip is on. How do I make sure the site properly implements Gzip. I am also going to enable far-future expiry ...

Garbled error page output using Gzip in ASP.NET / IIS7

I've implemented Rick Strahl's GZipEncodePage method on my site and it works great for the site itself. However, when my code throws an exception the "Server Error" page looks something like this: I've tried to hooking into Application_Error in an effort to remove the GZip headers but to no avail. How I can reverse the GZipping on e...
